Synthesis of atropisomeric 2-(1-aminoalkyl)-1-naphthamides by stereoselective addition of organolithiums to a 2-imino-1-naphthamide
摘要:
Unlike the corresponding aldehydes, 2-(N-methylformimino)-N,N-dialkyl-1-naphthamides react highly atroposelectively with simple organolithium reagents to give atropisomeric amines whose syn stereochemistry is thermodynamically preferred over anti. (C) 1999 Elsevier Science Ltd. All rights reserved.
