- In recent years, dihydrogen activation at non-metallic centers has received increasing attention. A system in which dihydrogen is trapped by a pyridylidene intermediate that is generated from a pyridinium salt and a base is now reported. The dihydropyridine formed in this process can act as reducing

- Highly torquoselective electrocyclizations of chiral 1-azatrienes are described. These 1-azatrienes contain an allylic stereocenter that is substituted with a silyl group and are derived in situ from condensation of γ-silyl-substituted enals with vinylogous amides. The ensuing stereoselective ring

- A gold-catalyzed highly regio- and chemoselective oxidative ring expansion of 2-alkynyl-1,2-dihydropyridines and its analogues using pyridine-N-oxide as the oxidant has been developed. Ring expansion proceeds through exclusive 1,2-migration of a vinyl or phenyl group, whereas no 1,2-H and 1,2-N migr

- … 1,4-dihydropyridine undergoes a head-to-tail [2+2] photodimerization that leads to the formation of anti-dimer, syn-dimer and cage dimer in solution. … The cage dimer is formed by the intramolecular reaction of syn-dimer, and is topochemical controlled by the nearest distance between potentially reacting double bonds, rotational angles of the building cyclobutane ring and the orientation of carbonyl ester. …
