摘要:
A novel C-3-symmetric arsine was synthesized from p-arsanilic acid in three steps. It was employed in the one-pot cyclopropanation of olefins with carbonyl-stabilized arsonium ylides formed in situ from methyl bromoacetate in the presence of NaHCO3. This new arsine demonstrates good stereoselectivity and activity in the one-pot cyclopropanation of arylidenemalononitrile. (C) 2012 Elsevier Ltd. All rights reserved.
