, p. 8939 - 8949 (2007/10/03)
Chiral 1,4-dihydropyridines were prepared by the regio- and stereoselective addition of ketene silyl acetals and organometallic reagents to pyridinium salts. In the addition reaction, an intramolecular interaction between the thiocarbonyl or carbonyl with
Synthesis of chiral 1,4-dihydropyridines by diastereoface-selective asymmetric addition to nicotinic amides
Yamada, Shinji,Ichikawa, Mayumi
, p. 4231 - 4234 (2007/10/03)
Diastereoface-selective asymmetric addition of organometallic reagents to pyridinium salts of 1 and 2 was performed to give chiral 1,4-dihydropyridines in good regio- and stereoselectivities. The absolute configuration of the newly-produced chiral center
