A short synthesis of some monoterpenoids from the adduct of myrcene with benzenesulfinyl chloride

摘要

The title adduct was converted into 1,2-epoxymyrcene; its cationic 5-exo-cyclization gave a (±)-hop ether having the iridane-type skeleton. Effective syntheses of a furanoterpene perillene and some functionalized cyclopentanoid monoterpenes regioisomeric to iridoids were elaborated using sulfur-containing geraniol derivatives easily accessible from the same adduct in a synthetic sequence including the Pummerer reaction and anionic cyclization
