Copper-catalyzed cyclization of Z-oximes into 3-methyl-1,2-benzisoxazoles
摘要:
A practical and effective room temperature copper-catalyzed cyclization of Z-oximes is developed. 3-Methyl-1,2-benzisoxazoles are obtained in 58-79% yields, Also, the Z-selective synthesis of o-bromo acetophenone oximes is presented for the first time. (C) 2009 Elsevier Ltd. All rights reserved.
