Various basicesters of nitrogen (2) and carbocyclic (3 and 4) analogs of cannabinoids were synthesized using dicyclohexylcarbodiimide in methylene chloride. The compounds in the three series werw studied in selected pharmacological tests in mice, rats, dogs, and cats. It was shown that making the basicesterfrom the phenol retains biological activity and can lead to a greater selectivity of action
Novel heterocyclic esters of benzopyranopyridines represented by the formula ##STR1## wherein R.sub.1 is hydrogen, lower alkyl, lower alkanoyl, cycloalkyl-lower alkyl, cycloalkyl-lower alkanoyl, lower alkenyl, lower alkynyl, halo-loweralkenyl, phenyl-lower alkyl, phenyl-lower alkenyl or phenyl-lower alkynyl; R.sub.2 is lower alkyl; R.sub.3 is an alkyl having one to twenty carbon atoms or a cycloalkyl-lower alkyl, Y is a straight or branched chain alkylene having one to eight carbon atoms, and R.sub.4 is a group of the formula ##STR2## a is an integer from 1 to 4, b is an integer from 1 to 4 and X is CH.sub.2, O, S or N--R.sub.5 with R.sub.5 being hydrogen or lower alkyl, with the limitation that when X is O, S or N--R.sub.5, a and b each must be 2 and R.sub.6 is hydrogen or a lower alkyl group bonded to a carbon in the ring; and the acid addition salts thereof.
