    Cationic cyclization of keto-epoxides mediated by zirconium(IV) tetrachloride: diastereoselective synthesis of cis-decalinols
    摘要:
    10-Methyl-cis-9-decalinols are important motifs in several natural products and key intermediates in total synthesis. Herein, we wish to describe a highly chemo- and diastereoselective cyclization of ketoepoxides leading to 10-methyl-cis-9-decalinols. This method based on the use of zirconium(IV) tetrachloride permits the access to a wide variety of cis-decalinols in good to excellent yields. The cationic cyclization could also be performed with chiral keto-epoxide with complete control of the diastereoselectivity affording cis-bicyclic tertiary alcohol with good enantiomeric excess. The chemo- and the diastereoselectivity are assumed to result from the ability of Zr(IV) to generate highly stable bidentic complexes with alpha-hydroxy-ketone intermediates. (C) 2011 Elsevier Ltd.

    2-烯基-1,3-二硫杂环戊酸酯的阳离子环化:反式十氢化萘的非对映选择性合成
    摘要:
    前所未有的和高度非对映6-内-三角函数的2-链烯基-1,3-二硫戊环化已经发展得到反式-decalins,存在于众多的二-和三萜类化合物的一个重要的支架。这个6-的新颖性内切- trig的环化手段在涉及2-链烯基-1,3-二硫戊环的分步机构,作为一个新的潜引发剂。有人建议,在硫缩酮暂时打开将TMSOTf的影响下,引发阳离子6-内- TRIG环化,并在C-C键形成和非对映选择性质子化后关闭,以终止该过程。DFT计算证实了这一机理性建议,并为观察到的非对映选择性提供了理论依据。该反应可耐受底物内的多种功能和亲核伴侣。我们还表明,一锅煮6-内- trig的环化,随后在原位1,3-二硫戊直接脱保护得到相应的酮。这一改进使得雷公藤多酚的总合成最短,雷公藤内酯的形式最短。

DFT calculations confirm this mechanistic proposal and provide a rationale for the observed diastereoselectivity. The reaction tolerates a wide range of functionalities and nucleophilic partners within the substrate. We have also shown that the one-pot
