    Bicyclic Polyketide Lactones from Chinese Medicinal Ants, Polyrhacis lamellidens
    摘要:
    Two new bicyclic polyketide lactones, polyrhacitides A (1) and B (2), were isolated from Chinese medicinal ants, Polyrhacis lamellidens, which have been used as an effective therapeutic agent to treat rheumatoid arthritis and hepatitis in China. Their absolute structures were elucidated on the basis of spectroscopic analyses and chemical evidence. The occurrence of polyketides with similar structures in plants of the Lamiaceae, Lauraceae, and Staphyleaceae indicates their significance in the study of chemical ecology.

    Two aliphatic polyketide natural products, polyrhacitides A and B, have been synthesized in a concise and highly stereoselective manner. The synthesis involved an auxiliary-based acetate aldol reaction to generate the initial stereogenic center and an iterative Wittig reaction, intramolecular oxa-Michael addition, and chelation-controlled reduction reaction as the key steps to generate additional stereocenters
