    Synthesis of (−)-Centrolobine by Prins Cyclizations that Avoid Racemization
    摘要:
    [GRAPHICS]The segment-coupling Prins cyclization avoids two of the problems common to other Prins cyclization protocols: side-chain exchange and partial racemization by reversible 2-oxonia Cope rearrangement. Model studies demonstrate the stereochemical fidelity of Prins cyclizations using alpha-acetoxy ethers compared with direct aldehyde-alcohol Prins reactions. Furthermore, we propose a mechanism for the racemization observed in some intermolecular Prins cyclizations. Two straightforward syntheses of optically pure (-)-centrolobine highlight the utility of Prins cyclizations.

  • Catalytic Asymmetric Intra- and Intermolecular Haloetherification of Enones: An Efficient Approach to (−)-Centrolobine
    作者:Pengfei Zhou、Yunfei Cai、Xia Zhong、Weiwei Luo、Tengfei Kang、Jun Li、Xiaohua Liu、Lili Lin、Xiaoming Feng

    alkenes (halogen = Cl, Br, I) has been realized by the use of chiral metal complexes of N,N-dioxides. In the presence of a chiral Fe(III) complex, a series of tetrahydropyran derivatives were obtained in good yields (up to 99% yield) with a high level of enantioselectivities (up to 97% ee). Promoted by a chiral Ce(III) complex, chiral oxepane derivatives could be given in good results. Moreover, the
    缺电子烯烃(卤素= Cl,Br,I)的催化不对称分子内和分子间卤代醚化反应已通过使用N,N'-二氧化物的手性金属配合物实现。在手性Fe(III)络合物的存在下,以良好的收率(最高99%的收率)和高的对映选择性(最高97%ee)获得了一系列四氢吡喃衍生物。在手性Ce(III)配合物的促进下,手性氧杂环丁烷衍生物可以得到很好的结果。而且,证明了使用MeOH作为亲核试剂,由Sc(III)配合物催化的查耳酮的分子间卤醚化。该方法也可以成功地应用于(-)-Centrolobine的合成。同时,提出了合理的反应机理。

    It has been demonstrated that an aryl-β-C-glycoside can be efficiently constructed via a sequence consisting of Brown asymmetric allylation, ring-closing metathesis, hydrogenation, nucleophilic addition, and stereoselective Et3SiH reduction. The antibiotic natural product ()-centrolobine was synthesized in this manner utilizing only five steps with an overall 53% yield.

    作者:Cheng-Hsia Angeline Lee、Teck-Peng Loh

    日期:2006.3
    An InCl3-mediated Prins cyclization of homoallylic alcohols with aldehydes has been established. The enantioselectivities of the trisubstituted tetrahydropyrans are almost retained through the suppression of epimerization. The synthetic value of this protocol is demonstrated by the total synthesis of ()-centrolobine.

    The application of 2-arylcyclopropylmethanols as substitutes to homoallyl aryl alcohols and their reactions with aliphatic aldehydes in the presence of SnCl4 in CH2Cl2 leads to an efficient Prins cyclization to generate cis-2,6-disubstituted tetrahydropyrans in high yields.

  • Prins Cyclizations in Silyl Additives with Suppression of Epimerization:  Versatile Tool in the Synthesis of the Tetrahydropyran Backbone of Natural Products
    作者:Kok-Ping Chan、Teck-Peng Loh
    DOI:10.1021/ol051951q
    日期:2005.9.1
    A catalytic Prins cyclization reaction has been developed. The involvement of trimethylsilyl halides offers a versatile route to the formation of cis4-halo-2,6-disubstituted tetrahydropyran rings. The problem of epimerization in Prins cyclization has also been addressed in the total synthesis of (-)-centrolobine using this methodology.
