摘要

The total synthesis of (+)-crassalactone B,(+)-crassalactone C,(+)-howiionol A,(+)- tricinnamate,(+)-goniofufurone, and (+)-dicinnamoyl goniofufurone is achieved by a 'chiron 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,(+)- ...
