    Synthesis of (2R,4R)-Supellapyrone, the Sex Pheromone of the Brownbanded Cockroach,Supella longipalpa, and Its Three Stereoisomers
    摘要:
    Supellapyrone [(2R,4R)-5-(2,4-dimethyl)-3-methyl-2H-pyran-2-one (1)], the female sex pheromone of the brownbanded cockroach (Supella longipalpa), and its three stereoisomers were synthesized by employing Iipase-catalyzed desymmetrization or enantiomer separation of syn- or anti-2,4-dimethylpentane- 1,5-diol (9) as the key step.

    日期:2008.3.1
    (S,R,R,S,R,S)-4,6,8,10,16,18-Hexamethyldocosane (1) was synthesized in 11% yield in 11 steps in the longest linear sequence from > or =98% pure (S)-beta-citronellal and 6 additional steps for the preparation of 11 in 23% yield from propene. Five of the six asymmetric carbon centers were generated catalytically and stereoselectively by the ZACA reaction (5 times), one lipase-catalyzed acetylation, and
    (S,R,R,S,R,S)-4,6,8,10,16,18-六甲基甲基二十二烷(1)以11%的产率按最长线性顺序从11%合成,大于或等于98%纯的(S)-β-香茅醛和6个额外的步骤,以11%的产率从丙烯制备11个。六个不对称碳中心中的五个是通过ZACA反应(5次),一种脂肪酶催化的乙酰化反应和两次色谱操作催化和立体选择性生成的。
