In this work we report our endeavors toward the development of an asymmetric synthesis of a 3,3-disubstituted isoindolinone, dimethyl 2-(1-methyl-3-oxoisoindolin-1-yl)malonate, via asymmetric cascade reaction of 2-acetylbenzonitrile with dimethylmalo

Detailed investigations concerning the organocatalytic (asymmetric) α-azidation of prochiral β-ketoesters were carried out. It was shown that the racemic version of such a reaction can either be carried out under oxidative conditions using TMSN3 as

A detailed screening of differently substituted chiral and achiral (thio)urea-containing quaternary ammonium salts revealed their potential as catalysts for the CO2-fixation with epoxides to obtain cyclic carbonates in high yields under operationally

A series of cationic polymers containing quaternary ammonium groups turned out to be powerful catalysts for the CO2-fixation of epoxides under an atmospheric pressure of CO2 at elevated temperature. A variety of differently substituted aromatic and a
