An efficient asymmetric synthesis of N-formylpiperidines via an organocatalytic Michael-aza-Henry-hemiaminalization reaction cascade of an aldehyde, a nitroalkene, and an N-arylideneformamide is reported. The reaction is triggered by diphenylprolinol trimethylsilyl ether and creates two C–C and one C–N bonds leading to the formation of highly enantio-enriched N-formylpiperidines with five contiguous...
An efficient and rapid (10–20min) one-pot synthesis of chemically and pharmaceutically interesting 1,4-oxathian-2-ones is reported. The protocol involves LiBr catalyzed regioselective ring-opening–ring-closing reaction cascade of terminal epoxides with α-mercaptocarboxylic acids at rt under solvent-free conditions. Recycling of the catalyst, atom economy, and formation of water as the only by-product...
