Bryophyte Constituents; 6: Synthesis of Herbertene-Derived Sesquiterpenes from Herberta adunca

Abstract

All articles of this category Efficient total syntheses are described for the racemic sesquiterpenes herbertenolide (2) , α -herbertenol (3) and β -herbertenol (4) from Herberta adunca . ent -Herbertenolide [(+) -2 ] was prepared from enantiopure (-)-ethyl (1 R )-1-methyl-2-oxocyclopentanecarboxylate (9) obtained from ethyl 2-oxocyclopentanecarboxylate (19) via reduction with baker’s yeast. bryophyte constituents - sesquiterpenes - herbertene - enantioselective synthesis - baker’s yeast
