Sesquiterpenes from the essential oil of the liverwort Conocephalum conicum

Three new brasilane type sesquiterpenes related to the known alcohol conocephalenol and the sesquiterpene alcohol presilphiperfolan-1-ol were isolated from a chemotype of the liverwort Conocephalum conicum collected in southern Germany and identified by NMR investigations, enantioselective gas chromatography and chemical correlations. In addition ent-(-)-dactylol, the enantiomer of a compound so far only found as a constituent of the Caribbean sea hare Aplysia dactylomela, was identified.

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

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.
