LIGNANS OF PIPER CUBEBA

Key Word Index - Piper cubeba; Piperaceae; diarylcyclobutane neolignans; dibenzylbutyrolactone lignan; O-ethyl cubebins; monoacetate of dihydrocubebin; structural determination. Seven additional compounds have been isolated from Piper cubeba and characterized as heterotropan, magnosalin, 2,4,5-trimethoxybenzaldehyde, α- and β-O-ethyl cubebins, 5''-methoxyhinokinin and the monoacetate of dihydrocubebin.The latter four compounds are new natural products.

Lipase-catalyzed esterification of a (±)-2,3-di(arylmethyl)-1,4- butanediol and its application to the synthesis of (S,S)-(+)-hinokinin

Racemic trans-2,3-di[(3,4-methylenedioxy)benzyl]-1,4-butanediol (dihydrocubebin) 6 was enantioselectively esterified using lipases as catalysts with vinyl acetate. Optically active (S,S)-1,4-butanediol 6 obtained was selectively oxygenated with a Fetizon reagent, affording (S,S)-(+)-hinokinin 9 in a high yield.
