A mutant of Aristolochene Synthase (AS), in which Tyr 92 was replaced by Val, produced the alicyclic beta-(E)-farnesene as the major product, indicating that cyclisation of FPP is controlled by Tyr 92 in AS.

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.
