  摘要：

  The total synthesis of (+)-crassalactone B (+)-crassalactone C (+)-howiionol A (+)-tricinnamate (+)-goniofufurone and (+)-dicinnamoyl goniofufurone is achieved by a chit-on approach starting from diacetone D-glucose (DAG) Mitsunobu inversion Wittig olefination and ring closing metatheses were used as key steps for (+)-howiionol A and (+)-tricinnamate Meldrum s acid was used for the synthesis of (+)-crassalactone C (+)-goniofufurone and (+)-dicinnamoyl goniofufurone Yamaguchi esterification was used for (+)-crassalactone B while a Grignard reaction followed by concomitant deallylation was first reported in the synthesis of (+)-dicinnamoyl goniofufurone (C) 2010 Elsevier Ltd All rights reserved
