Abstract
Condensation of 1-cyanomethyl-2,3,3-trimethyl-3H-indolium perchlorate with ortho-hydroxy-substituted aromatic aldehydes afforded 1-cyanomethylindoline spiropyrans. The latter underwent rearrangement to bridged 1,3-benzoxazepino[3,2-a]indoles on treatment with a base. The mechanism of the rearrangement includes generation of a carbanion stabilized by a cyano Group.
