In recent years several approaches to hydroazulenes involving efficient and ingenious synthetic designs have been developed. 1 We report here a new route to 6-methyl-bicyclo(5,3,O)-deca-l,6-dien-3-one (4).2 Treatment of the bicyclic enedione (1) with dimethyloxosulfoniu methylide (DMSM)3 in dimet%l

โฆ Synopsis
The epidithiapiperazinedione ring is the functional group common to natural products in the gliotoxin-sporidesmin class. We reported a general synthetic method to construct the epidithiapiperazinedione system1 and demonstrated its applicability in a total synthesis of dehydrogliotoxin, 2 sporidesmin A, 3 sporidesmin B, 4 and gliotoxin.
