Reactions of N-and C-Alkenylanilines: VII. Synthesis of Indole Heterocycles from Products of Reaction between N-Mesyl-2-(1-alken-1-yl)anilines and Halogens
Heterocyclic compounds of the 4H-3,1-benzoxazine and cyclopenta[b]indole series were synthesized by oxydation of N-acyl derivatives of 2-(1-alkenyl)anilines with hydrogen peroxide. The structure of the oxidation products is determined by the reaction conditions, substituent in the ortho-position of the aromatic ring, protecting group, and alkenyl radical structure.
