    摘要: Vasodilatory eburnamine-type alkaloid esters of the formula (I) ##STR1## and salts and quaternary derivatives thereof, wherein X.about.Y REPRESENTS A =CH=CH- or ##STR2## R represents a C.sub.1-6 alkoxycarbonyl group optionally substituted with a hydroxy group or with a halogen atom, further an alkenyloxycarbonyl, aryloxycarbonyl, aralkoxycarbonyl group or an acylated primary alcohol group, especially apovincaninic acid ethyl ester, have been prepared by various methods of esterification.
