Synthesis of chiral N,N′-disubstituted 1,2-benzenediamines from o-dibromobenzene
摘要:
Palladium-catalyzed amination of o-dibromobenzene provided chiral N,N'-disubstituted 1,2-benzenediamines in good to excellent yields. The amination was executed stepwise and in one pot to give unsymmetrically and symmetrically substituted 1,2-benzenediamines. Incorporation of chiral primary amines was possible without racemization using catalytic Pd(2)dba(3)-BINAP. (C) 2000 Elsevier Science Ltd. All rights reserved.
