Abstract
Reaction of 4-(1-ethyl-1-propenyl)morpholine with benzylideneanilines in acetic acid provided 1,2,4,6,7-pentaaryl-3,5,7a-trimethyl-1,2,3,4,7a,8-hexahydro-4-aza-s-indacene in decent yield. The reaction mechanism involving the conrotatory cyclization of an intermediate pentadienyl cation has been proposed.
