Asymmetric palladium(0)-mediated synthesis of 2-vinylchroman
摘要:
Optically active 2-vinylchroman was synthesized from the corresponding hydroxy allylic carbonate by palladium-catalyzed cyclization in the presence of various chiral ligands. Enantioselectivity of up to 53% was obtained using NMDPP as the chiral phosphine. (C) 1999 Elsevier Science Ltd. All rights reserved.
