BIOMIMETIC CYCLIZATION OF HEDYCARYOL DERIVATIVES. UNEXPECTED CYCLIZATION OF PHENYL SULFIDES WITH METHYL IODIDE

Kodama, Mitsuaki,Shimada, Kazuaki,Ito, Sho

, p. 1523 - 1526 (2007/10/02)

Four isomeric hedycaryol phenyl sulfides, when reacted with MeI, 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.
