Title compds. (I; R1 = H, benzyl, benzoyl, C1-5 alkanoyl; R4 = H, C1-6 alkyl; R5 = H, methyl, ethyl; R6 = H, carbobenzyloxy, formyl, C2-5 alkanoyl, C1-6 alkyl; Z = C1-9 alkylene; W = H, methyl, pyridyl, piperidyl), useful as analgesics, were prepd. by the birch reduction of II. Thus, d,1-5,6,6a,7-tetrahydro-1-hydroxy-6 -methyl-3-(4-phenylbutyloxy)-benzo[3 -quinolin-9(8H)-one was reduced with lithium and ammonia, and acylated to give d,1-trans-5,6,6a,7,10,10a - hexahydro-1-acetoxy-6β-methyl-3-(4-phenylbutyloxy)benzo[c quinolin-9(8H)-one
