  Asymmetric synthesis of tanshindiol A.

  摘要：

  The ultrasound-promoted Diels-Alder reaction of 3-methyl-4,5-benzofurandione (10) with appropriately substituted vinylcyclohexenes has led to the synthesis of tanshindiol A (9), a minor component of the Chinese traditional medicine, Dan Shen, prepared from the roots of Salvia miltiorrhiza Bunge. The regioselectivity of the cycloaddition was enhanced by the ultrasonication and was also strongly influenced by the solvent. The asymmetric synthesis of (+)-(4R)-tanshindiol A [(+)-(4R)-91, the naturally occurring enantiomer, proceeded from the optically enriched methyl 6-(benzoyloxy)-1-vinylcyclohexene-6-carboxylate [(-)-(R)-15] or 6-hydroxy-6-(hydroxymethyl)-l-vinylcyclohexene acetonide [(+)-(R)-291 (both 92% ee). Enantioselectivity in the preparation of these diene systems was accomplished by the benzoyl peroxide quench of the lithioenamine derived from methyl 1-oxocyclohexane-2-carboxylate and (S)-valine tert-butyl ester. This procedure, adapted from Koga's asymmetric alkylation of alpha-alkyl beta-keto esters, proved highly effective in preparing the necessary tertiary alcohol in protected form and with high optical purity.

  We have developed the stereoselective synthesis of 2-oxaspiro[m,n]alkane derivatives using the Prins-pinacol annulation of alkene diols with a wide range of aliphatic or aromatic aldehydes and ketones. This approach was further applied for the synthesis of oxatricyclic ring system.

  我们已经开发了使用具有多种脂族或芳族醛和酮的链烯二醇的Prins-频哪醇环化技术，对2-oxaspiro [ m，n ]烷烃衍生物进行立体选择性合成。该方法被进一步应用于乙三环系统的合成。

  Direct oxidation of racemic beta-hydroxyketones 1a-c under Sharpless oxidation conditions resulted in the enantiomeric alpha,beta-dihydroxyketones 2a in 97% ee, 2b in 86% ee and 29 in 95% ee respectively, in 37-58% of isolated yield. The oxidation is assumed to proceed via an allylic enolate intermediate. (C) 1997 Elsevier Science Ltd.
