摘要:
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.
