Synthesis of sesquiterpenes, occidentalol, chamaecynone and related compounds characterised by a cis-eudesmane structure
Abstract
In continuation of our synthetic work for constructing the cis-decalin skeleton by a double Michael annulation using 3-methyl-4-methylenecyclohex-2-enone and its congeners with dimethyl 3-oxoglutarate, the sesquiterpenes, occidentalol, chamaecynone, and related compounds have been synthesised in a stereoselective manner.
