Abstract

Transformation of Indoline Spiropyrans to Bridged 1,3-Benzoxazepino[3,2-a]indoles via Carbanions Stabilized by a CyanoGroup. -The mechanism of the rearrangement reaction is discussed. The assumed process via a carbanion stabilized by the cyano group is supported by semiempirical calculations. -(SACKUS*, A.; VALAITYTE, E.; AMANKAVICIENE, V.; BERG, U.; SCHICKTANZ, C.; SCHLOTHAUER, K.; Chem.
