Abstract
Process for the preparation of new quinoleicin compounds characterized in that a compound of general formula ** is condensed wherein r1 and r2 represent alkoyl radicals lower and n represents an integer from 1 to 4 and in which adjacent r1 o groups can be linked together so as to form an alkoylenedioxy group and the bond between carbon atoms 2 and 3 can be saturated with a beta-phenyl-ethylamine of general formula ** in which r3 represents a lower alkoyl radical and m represents zero or an integer from 1 to 4 and wherein the groups r3 o may be linked together so as to form an alkoylenedioxy group and the nucleus may be partially or totally hydrogenated, the acid amide obtained is subjected to cyclization by treatment with dehydrating agents and is hydrogenated the cyclization product.
