Photochemistry of ethyl 2-cyano-1,2-dihydroquinoline-1-carboxylates (Reissert compounds): synthesis of 2-cyanomethylinodole-1-carboxylates
Abstract
Irradiation of ethyl 2-cyano-1,2-dihydroquinoline-1-carboxylates (Reissert compounds) gives ethyl N-[o-(3-cyanoallenyl)phenyl]carbamats, which are readily converted into ethyl 2-cyanomethylindole-1-carboxylates by treatment with alumina.
