Abstract
The reaction of 2- and 4-vinylpyridines with 3-substituted phenacylpyridinium ylids takes place regioselectively with the formation of only 6-substituted 1-pyridyl-3-aroylindolizines. The reaction of the same ylids with dimethyl acetylenedicarboxylate gives a mixture of isomeric 6- and 8-substituted 1,2-dicarbomethoxy-3-aroylindolizines. In the analogous reaction of 2-bromo-1-phenacyl-pyridinium ylid, in addition to the corresponding 5-bromoindolizine, the product of its spontaneous cyclization, viz., 4,5-dicarbomethoxy-6-oxo-(6H)-10c-azaacephenanthrylene, was isolated.
