The reaction of the bicyclic polyfunctional electrophilic system – 1-ethoxy-5-methyl-3,8-diphenyl-1-pyrano[3,4-]pyran-7-ium perchlorate with heterocyclic and aromatic acid hydrazides leads to the corresponding N-aminopyridinium ylides . The reaction conditions have been optimized and a mechanism for the formation of the ylides has been proposed.

Sulfamide was desymmetrized by a reaction with aldehydes to give -sulfamoylimines. The latter reagents were successfully introduced into diastereo- and chemoselective transformation with cyclic anhydride using the Castagnoli-Cushman reaction to give unprotected -sulfamoyl tetrahydroisoquinolonic (THIQ) acids under simple metal-free protocol. Thereby, the first general approach to the direct assembly

This report describes the synthesis and study of two new amino-containing donor-acceptor lactone-bridged biaryls as pi-expanded, or benzannulated, coumarins based on the 6H-benzo[]chromen-6-one (benzo[]coumarin) structural unit. These fluorescent and planar compounds exhibit strong intramolecular charge transfer (ICT) through the conjugated biaryl unit via a diethylamino donor on one arene and either
