The ortho-substituted N,N-diacetylaniline as a selective acetylating reagent
摘要:
Selective acetylation of the less hindered amino group in the presence of the more hindered amino group with the use of 2-trifluoromethyl-N,N-diacetylaniline 2c is described. This acetylation with 2c yielded the corresponding less hindered monoacetamide exclusively, simply, conveniently, and in good yields. (C) 1997 Elsevier Science Ltd.
