    Ramariolides A–D, Antimycobacterial Butenolides Isolated from the Mushroom Ramaria cystidiophora
    摘要:
    Four butenolides, ramariolides A-D (1-4), have been isolated from the fruiting bodies of the coral mushroom Ramaria cystidiophora. Their structures were elucidated by analysis of ID and 2D NMR data and a single-crystal X-ray diffraction analysis of 1, and their absolute configurations were established using Mosher's method. The major metabolite, ramariolide A (1), which contains an unusual spiro oxiranebutenolide moiety, showed in vitro antimicrobial activity against Mycobacterium smegmatis and Mycobacterium tuberculosis.

  • Asymmetric Synthesis of Ramariolides A and C through Bimetallic Cascade Cyclization and <i>Z</i>–<i>E</i> Isomerization Reaction
    作者:Pratik Pal、Samik Nanda
    DOI:10.1021/acs.orglett.7b00202
    日期:2017.3.3
    A short and flexible asymmetric synthesis of ramariolides A and C was accomplished. A bimetallic catalytic system consisting of Pd–Cu-mediated cascade cyclization, unprecedented Z–E isomerization by a Ru-based metathesis catalyst, and late-stage stereoselective epoxidation are the key steps involved in the synthesis.
