Stereospecific Synthesis of (−)-β-Turmerone and (−)-Bisacurol
摘要:
The structure of (+)-beta-turmerone ((+)-1a), a constituent of the rhizomes of Curcuma longa LINN., and Curcuma xanthorriza, is established as (1'R,6S)-2-methyl-6-(4'-methylenecyclohex-2'-en-1'-yl)hept-2-en-4-one by synthesis of its enantiomer (-)-1a, and of the corresponding (1'S,6S)-diastereoisomer (+)-1b as well. In a stereospecific seventeen-step procedure, the monoterpene diols 2a and 2b of well-established configuration are convened into the target compounds (-)-1a and (+)-1b, respectively. Moreover, (-)-bisacurol (-)-3a(II), the enantiomer of another bisabolane sesquiterpene derived from Curcuma xanthorriza, is obtained as a single stereoisomer and shown to be (1'S,6R)-2-methyl-6-(4'-methylenecyclohex-2'-en-1'-yl)hept-2-en-4-ol, the relative configuration at the remaining OH-substituted chiral center C(4) still being unknown.
