Abstract

Abstract All isomers of (monomethyl) benzo [a] quinolizinium salts including five new monomethyl derivatives were prepared by photocyclization, sulfur extrusion, or cyclodehydration reaction, and their aldol-type condensation was examined. The 2-and 4- methyl derivatives 3b and 3c reacted with p-methoxybenzaldehyde in the presence of piperidine to yield trans-(p-methoxystyryl) benzo [a] quinolizinium salts 11. The other ...
