摘要:
A general method for the preparation of various 3,4-fused-spiro[furan-5(5H),4'-piperidini-2-one with high yield is reported. The formation of spiro[furarione-piperidine] structure was achieved by a Suzuki coupling, followed by an iodolactonization reaction. (C) 2009 Elsevier Ltd. All rights reserved.
