Total synthesis of (±)-cis-5-hydroxycalamenene

A total synthesis of (±)-cis-5-hydroxycalamenene 1 has been achieved from tetralone 5, which in turn was prepared from 5-methoxy-α-tetralone 3. Grignard reaction of compound 5 with isopropylmagnesium chloride, followed by dehydration and aromatization, provided the substituted naphthalene 7 whose conversion to (±)-cis-5-hydroxycalamenene 1 was accomplished by demethylation, formylation, and hydrogenation.

Studies on aromatic sesquiterpenes. XII. Synthesis of (±)-cis-5-Hydroxycalamenene

Starting from o-cresol, (±)-cis-5-hydroxycalamenene was synthesized through 4-isopropyl-5-methoxy-6-methyl-1-tetralone as a key intermediate and identified with the natural compound spectroscopically.
