Introduction
Our research is dedicated towards the development of new catalytic methods in order to improve functional group tolerance, selectivities and sustainability compared to conventional non-catalytic approaches. Additionally, these newly established methods are applied in the synthesis of bioactive compounds such as pharmaceuticals and natural products.

Article
Full-text available
Herein, the first organocatalytic method for the transformation of non‐derivatized formic acid into carbon monoxide (CO) is introduced. Formylpyrrolidine (FPyr) and trichlorotriazine (TCT), which is a cost‐efficient commodity chemical, enable this decarbonylation. Utilization of dimethylformamide (DMF) as solvent and catalyst even allows for a rapi...

Nucleophilic Substitutions (S N ) account to the most essential and frequently applied chemical transformations. S N ‐reactions allow to forge C‐C, C‐O, C‐N and C‐Cl bonds, for example, from natural abundant starting materials such as alcohols and carboxylic acids. Products of S N ‐reactions are ubiquitous and find inter alia application as pharmac...
Article
Full-text available
A novel, broadly applicable method for the amide C-N and ester C-O bond formation is presented based on formylpyrrolidine (FPyr) as Lewis base catalyst. Thereby, trichlorotriazine (TCT), which is the most cost-efficient reagent for OH-group activations, was employed in amounts of ≤40 mol% with respect to the starting material (100 mol%). The new ap...
Article
A practical method for the nucleophilic substitution (SN) of alcohols furnishing alkyl chlorides, bromides, and iodides under stereochemical inversion in high catalytic efficacy is introduced. The fusion of diethylcyclopropenone as a simple Lewis base organocatalyst and benzoyl chloride as a reagent allows notable turnover numbers up to 100. Moreov...
Article
A simple formamide catalyst facilitates the efficient transformation of alcohols into alkyl chlorides with benzoyl chloride as the sole reagent. These nucleophilic substitutions proceed through iminium-activated alcohols as intermediates. The novel method, which can be even performed under solvent-free conditions, is distinguished by an excellent f...
Article
The Cover Feature shows the Lewis base‐catalyzed activation of alcohols for nucleophilic substitutions (SN) using phenyl chloroformate (PCF) as inherently safe phosgene substitute. In their Full Paper, B. Zoller et al. explain that SN‐reactions are typically facilitated by stoichiometric reagents, which effect an enhanced thermodynamic driving forc...
Article
Full-text available
Nucleophilic substitutions (S N ) are typically promoted by acid chlorides as sacrificial reagents to improve the thermodynamic driving force and lower kinetic barriers. However, the cheapest acid chloride phosgene (COCl 2 ) is a highly toxic gas. Against this background, phenyl chloroformate (PCF) was discovered as inherently safer phosgene substi...
Article
Full-text available
Radicals can be generated at room temperature by means of visible light, when certain catalysts are engaged. Conventional protocols are mainly limited to the formation of radicals that are stabilized by adjacent electron withdrawing groups. Novel methods also enable the formation of non-stabilized radicals from naturally abundant alcohols and amine...
Article
Full-text available
Mit sichtbarem Licht lassen sich in Gegenwart bestimmter Katalysatoren Radikale bei Raumtemperatur erzeugen. Bisher waren diese Methoden auf Radikale begrenzt, die durch elektronenziehende Substituenten stabilisiert sind. Neuerdings sind auch nicht stabilisierte Radikale aus Alkoholen und Aminen zugänglich.
Article
The Cover Feature shows Lewis base catalyzed nucleophilic substitutions (SN) engaging non‐activated alcohols, carboxylic acids, aldehydes, and epoxides as substrates. In fact, SN‐transformations are of fundamental significance in chemistry. Especially in the last decade, powerful catalytic approaches for SN‐type C–C, C–N, C–O, and C–Cl bond formati...
Article

Certain micro algae produce so-called sulfolipids, a class of polychlorinated natural products. Consumption of these cell toxins by humans by means of mussels and shell fish can cause seafood poisoning. The rich stereochemistry and structural complexity of these natural products makes their synthesis challenging. Recent reports allow for an insight...

Boron-containing Lewis acids such as boronic acids, borates and boric acid allow for the direct dehydrative condensation of carboxylic acids with amines to afford amides. These catalysts not only enable the formation of peptide C-N bonds without epimerization, but also tolerate acid labile functional groups.
Article
Herein, a novel method for the transformation of aldehydes into geminal dichlorides based on phthaloyl chloride as reagent and N-formylpyrrolidine as Lewis base catalyst is disclosed. Given the mild reaction conditions, the current protocol is distinguished by high levels of functional group compatibility and scalability and is operationally simple...

Borhaltige Lewis‐Säuren wie Boronsäuren, Borate oder Borsäure ermöglichen, Carbonsäuren und Amine direkt zu Amiden zu kondensieren. Mit diesen Reagenzien lassen sich nicht nur Peptidbindungen ohne Verlust an Stereoisomerenreinheit knüpfen, sondern die Reaktion funktioniert auch mit säureempfindlichen funktionellen Gruppen.
Article
Herein, a method for the nucleophilic substitution (SN) of benzyl alcohols yielding chloro alkanes is introduced that relies on aromatic sulfoxides as Lewis base catalysts (down to 1.5 mol%) and benzoyl chloride (BzCl) as reagent. A systematic screening of various sulfoxides and other sulfinyl containing Lewis bases afforded methyl(2‐methoxyphenyl)...
Article
Substitution reactions belong to the most fundamental transformations in chemistry. However, they are commonly restricted by a poor sustainability, as at least one waste byproduct is formed. Herein, a general and highly efficient formamide‐catalyzed method for nucleophilic substitution of alcohols furnishing alkyl chlorides is presented, in which t...
Article
Herein, a general formamide catalyzed protocol for the efficient transformation of alcohols into alkyl chlorides, which is promoted by substoichiometric amounts (down to 34 mol%) of inexpensive trichlorotriazine (TCT), is introduced. Importantly, the present work is the first example of a TCT mediated dehydroxychlorination of an OH-group containing...

A simple formamide catalyst facilitates the efficient transformation of alcohols into alkyl chlorides with benzoyl chloride as the sole reagent.
Article
Nucleophilic substitutions (SN) at sp³-hybridized carbon centers are one of the most fundamental type of transformation in organic synthesis. Taking the importance of bimolecular SN reactions into account, catalytic variants must be considered as underdeveloped. This review highlights the most recent progress in the emerging field of Lewis base cat...

A practical and scalable synthesis of a Fmoc-protected tricyclic dipeptide mimetic (6), that is, a 1,4-diaza-tricyclo-[8.3.0(3,7)]-tridec-8-ene derivative resembling a rigidified di-L-proline in a polyproline type II (PPII) helix conformation, was developed. The strategy is based on a Ru-catalyzed ring-closing metathesis of a dipeptide (4) prepared...
Article
Solubilization of proline as the triethylammonium salt allows N-protection (as the Boc, Cbz or Moc derivative) and subsequent esterification or amidation of the carboxy terminus to be performed in an efficient one-pot fashion. Based on this concept, highly practical protocols were developed to prepare a series of proline derivatives (including Pro-...
Article
A practical four-step synthesis of 3-alkyl-, vinyl-, and aryl-substituted proline derivatives, which are important building blocks for conformationally restrained peptide analogs, was developed. The method relies on a Cu-catalyzed 1,4-addition of Grignard reagents to N-protected 2,3-dehydroproline esters, efficiently prepared in a new one-pot proto...
