Article abstract of DOI:10.1248/cpb.45.869

Optically active 2-hydroxymethyl-1,4,dihydropyridines were obtained by lipase-catalyzed hydrolysis or transesterification of racemic materials. Chiral NB 818 and nilvadipine have been synthesized from chiral 2- hydroxymethyl-1,4-dihydropyridine. On the ot
