ABSTRACT: This review article is the second in a series covering advances in the synthetic and molecular recognition chemistry of calixpyrrole macrocycles (meso-octasubstituted porphyrinogens). Significant progress has been made in the last three years in the use of calixpyrroles as redox-active or optical sensors for anions. This period has also been marked by a number of preparative advances, including the synthesis of N-confused calixpyrroles, the synthesis of extended cavity calixpyrroles, and the synthesis of ‘higher order’ or ‘expanded’ calix[n]pyrroles (n>4).Chemical Communications 01/1998; 222(1-222):57-102.

ABSTRACT: This review describes covalent and non-covalent combinations of building blocks, e.g. calixarenes, resorcinarenes, cyclodextrins, porphyrins, and cyclotriveratrylenes, leading to well-defined large (receptor) molecules.European Journal of Organic Chemistry 12/1998; 1998(12):2689-2702.

Article: Functionalized Calixpyrroles[Show abstract] [Hide abstract]
ABSTRACT: The synthesis and properties of a number of functionalized calixpyrroles are described. To date, two generalized preparative approaches have been pursued. The first involves modifying the basic pyrrole-plus-ketone synthesis of calixpyrrole by using modified precursors or by co-condensing more than one ketone with pyrrole. The second approach relies on the reaction of a pre-formed calixpyrrole with an electrophile. In both cases, the resulting species can be subject to further manipulation. In this way a range of structures, including ones bearing ancillary recognition subunits, electro- or photochemical reporter groups, and/or water solubilizing substituents may be obtained. Solid supports bearing calixpyrroles may also be produced in this way.Pure and Applied Chemistry 12/1998; 70(12-12):2401-2408. DOI:10.1351/pac199870122401 · 2.49 Impact Factor
