Synthesis and Biological Activities of Optical Isomers of 2-(4-Diphenylmethl-1-piperazinly)ethyl 5-(4,6-Dimethyl-2-oxo-1,3,2-dioxaphosphorinan-2-yl)-1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3-pyridinecarboxylate Dihydrochloride(NIP-101).
Synthesis and Biological Activities of Optical Isomers of 2-(4-Diphenylmethl-1-piperazinly)ethyl 5-(4,6-Dimethyl-2-oxo-1,3,2-dioxaphosphorinan-2-yl)-1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3-pyridinecarboxylate Dihydrochloride(NIP-101).
An optical isomer of a compound having the formula: ##STR1## wherein the two methyl groups at 4- and 6-positions of the dioxaphosphorinane ring assume trans configurations to each other, which has a levo-rotatory angle of optical rotation attributable to the asymmetric carbon atom at 4-position of the dihydropyridine ring, and a pharmaceutically acceptable salt thereof.
