Bergman, Jan,Eklund, Nils
, p. 1445 - 1450 (2007/10/02)
The unsymmetrical N,N,N-trimethyl tris-indolobenzene 3 has been synthesized by several routes, including cyclotrimerization of the O-acetate of indoxyl.This condensation involves a 32 rearrangement of the precursor formed in situ.Similar Wagner-Meerwei
