摘要：
The first synthesis of cis-enediynes 11 from 1,5-diyne 7 is achieved by treatment with 1 equivalent of CSA in CH2Cl2 at 20 degrees C in the presence of ROH or RSH to provide 11 as the major products in good yield. An 11-membered ring enediyne 15 was prepared similarly in 47% yield. Copyright (C) 1996 Elsevier Science Ltd
