摘要：

The transesterification of ketoesters using zinc and iodine is described. The reaction has been done on a variety of alcohols and phenols. Alcohols furnish transesterified products whereas phenols gave 4-methylcoumarins. The method is highly promising compared with existing methods. (C) 2002 Elsevier Science Ltd. All rights reserved.
