3-Cyanopiperidin-2,6-diones are key intermediates in the synthesis of several drugs and natural products. We developed one-pot synthesis of 3-cyanopiperidin-2,6-diones by Knoevenagel condensation of cyanoacetic acid and aldehydes, followed by additio

A systematic study on the influence of Lewis acid, solvent, and temperature on the stereochemical course of the Ugi reaction was performed to find conditions in which the isocyanides derived from enantiopure α-amino acids do not racemize. After a se

The Passerini reaction offers an easy access to depsipeptides, when both acid and isocyanide are derived from of.-amino acids. However, racemisation of isocyanides derived from alpha-amino acid esters severely limits their use in the Passerini reacti
