Synthesis of N,N'-Diacylindigotins (N,N'-Diacyl-2,2'-bi-indolinylidene-3,3'-diones) via an Oxidative Oxygen-to-Nitrogen Acyl Shift of O,O'-Diacyl-leucoingigos(3,3'-Diacyloxy-2,2'-bi-indolyls)

O,O'-Diacyl-leucoindigos (3f-j), which were readily obtained by the reaction of leucoindigo disodium salt (4) with acyl chlorides, underwent rapid oxidation by 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) to fenerate the indigo chromophore with concomitant shift of the acyl groups intramolecularly from oxygen to nitrogen.A number of N,N'-diacylindigotins with functionalized acyl groups were prepared by this method and the direct N-acylation method .A large bathochromic shift of the visible absorption band in the cis form of N,N'-diacylindigotins with bulky acyl groups (2c), (2d), and (2j) was observed which suggested that the electronic structure of the indigo chromophore is perturbed by the steric constraint of the N-acyl groups.
