  Cyclopropylation of arylamines at the 2-position with cyclopropylmagnesium carbenoids

  摘要：

  Direct cyclopropylation of arylamines at the 2-position with 1-chlorocyclopropyl phenyl sulfoxides was achieved. The reaction of N-lithio arylamines with cyclopropylinagnesium carbenoids, which are generated from 1-chlorocyclopropyl phenyl sulfoxides with i-PrMgCl via the sulfoxide-magnesium exchange reaction, is the key of this procedure, This method offers an unprecedented way for the synthesis of arylamines having a cyclopropane ring at the 2-position directly from arylamines.

  Treatment of magnesium cyclopropylidenes, which were generated from 1-chlorocyclopropyl phenyl sulfoxides with isopropylmagnesium chloride in THF at -78 degrees C, with N-lithio arylamines gave arylamines cyclopropylated at the 2-position in moderate to good yields. Use of the magnesium cyclopropylidenes having at least one substituent was found to be essential to this cyclopropylation. This procedure offers a novel synthesis of arylamines having a cyclopropane ring at the 2-position directly from arylamines. (c) 2007 Elsevier Ltd. All rights reserved.
