  • A divergent strategy to the withasomnines
    作者:Robert S. Foster、Jianhui Huang、Jérôme F. Vivat、Duncan L. Browne、Joseph P. A. Harrity
    DOI:10.1039/b910632d
    日期:——
    A concise synthesis of three members of the withasomnine family of natural products is reported. The synthesis features a regioselective sydnone–alkynylboronate cycloaddition followed by Suzuki cross coupling and silyl group removal, and marks the first divergent approach to this family of pyrazole based natural products.

    Abstract

    Microwave irradiation of 2-alkynyl-5-(phenyl or alkyl)tetrazoles affords 2-(phenyl or alkyl)-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazoles via intramolecular [3+2] cyclization of nitrile-imine intermediates. In the present method, the use of 5-alkyltetrazoles as the starting materials is more advantageous because of the difficulties associated with conventional photoreactions. From 2-phenylalkynyl-5-methylthio-1H-tetrazoles, the reaction efficiently produces 2-methylthio-3-phenyl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazoles. The procedure using the methylthio group is applied to the total synthesis of three naturally occurring withasomnines. The method is also extended to the construction of molecules in which bicyclic pyrazoles are fused to six- to eight-membered rings.

    摘要:使用微波辐照2-炔基-5-(苯基或烷基)四唑,通过腈-亚胺中间体的分子内[3+2]环化,得到2-(苯基或烷基)-5,6-二氢-4H-吡咯并[1,2-b]吡嗪。在本方法中,使用5-烷基四唑作为起始物质更具优势,因为传统光反应存在困难。从2-苯基炔基-5-甲基-1H-四唑,该反应有效地产生2-甲基-3-苯基-5,6-二氢-4H-吡咯并[1,2-b]吡嗪。使用甲基团的程序应用于三种天然存在的威莎莫宁的全合成。该方法还扩展到将双环吡嗪融合到六到八元环中构建分子。
