ABSTRACT A new silyl-based reagent has been developed for "catch and release" immobilization, combining click chemistry with silyl protection. The traditional "all carbon" attachment to solid supports in a silyl type linker was substituted with a stable triazole, easily assembled using the CuAAC reaction. The methodology introduces a novel ethynyldiiospropylchlorosilane reagent (EDIPS-Cl) as a functionalized protecting group linker.

    ABSTRACT: C-Linked antifreeze glycoprotein (C-AFGP) analogues have been shown to have potent ice recrystallization inhibition (IRI) activity. However, the lengthy synthesis of these compounds is not amenable to large-scale preparation for the many commercial, industrial, and medical applications that exist. This paper describes the synthesis of triazole-containing AFGPs using a convergent solid-phase synthesis (SPS) approach in which multiple carbohydrate derivatives are coupled to a resin-bound synthetic peptide in a single step. Modified "Click" conditions using dry DMF as solvent with catalytic Cu(II), sodium ascorbate, and microwave radiation afforded the synthesis of AFGP analogues 9-12 in 16-54% isolated yield. Compound 9 demonstrated no IRI activity, while compounds 10, 11, and 12 were moderate inhibitors of ice recrystallization. These results suggest that, while the triazole group is a structural mimetic of an amide bond, the amide bond in C-AFGP analogue 3 is an essential structural feature necessary for potent IRI activity.

    ABSTRACT: A synthesis of anthracycline aglycone derivatives is described. The key step utilizes a powerful domino carbopalladation approach and subsequent ring closure. During this process two of the four rings of the anthracycline scaffold are formed. Differently substituted carbohydrates and dialkyne chains serve as versatile and simple starting materials for the reaction sequence. Diverse building blocks lead to a variety of different products and a broad range of structural diversity.
