Four isomeric hedycaryol phenyl sulfides, when reacted with Mel, yielded eudesmol derivatives with different stereochemistry from that of the acid cyclization products of the corresponding hedycaryols. New stereoisomers of α- and β-eudesmols, β-dehydroparadisiol and a defensive substance of termite were synthesized. Nephthenol phenyl sulfide yielded a 14-membered tetraene.
