摘要

A general synthetic approach to a wide variety of 2, 5-disubstituted 3, 6-diamino-l, 4- benzoquinones was developed. Bromanil was diaminated with ammonia, and adjacent NH2 and OH groups were protected as benzoxazoles by treatment with a carboxylic acid chloride followed by a polyphosphate ester cyclization-dehydration. The resulting 2, 5- dibromobenzobis (oxazoles) were monolithiated by halogen-metal exchange with n- ...
