  Abstract Four new bitter iridoid glucosides, including three bis-iridoids, were isolated from Viburnum urceolatum and their structures elucidated. They are composed of loganin or deoxyloganin as the aglucone esterified with either aromatic glucoside or with glucose in the 4-position.

  aglycone moiety of loganin that has a 5,6-fused bicyclic framework and exhibits a wide range of interesting biological activities. A gram-scale synthesis of loganetin has been accomplished from the readily accessible S-(+)-carvone. The key reactions of the synthesis are a Favorskii rearrangement to introduce four stereocenters and a sulfuric acid-meditated deprotection/cyclization reaction to assemble the

  Loganetin 是马钱素的糖苷配基部分，具有 5,6-稠合双环框架并表现出广泛的有趣生物活性。已从易于获得的S -(+)-香芹酮中完成了 loganetin 的克级合成。合成的关键反应是 Favorskii 重排以引入四个立体中心和硫酸介导的脱保护/环化反应以组装具有完全立体选择性的敏感二氢吡喃环。这项工作还使我们能够成功合成 C1 甲氧基马钱子素和马钱子素的对映异构体。

  Structural modifications in iridoid glycosides and evaluation of their efficacy on adhering capability (in vitro) of immature hamster uterine epithelial cells to the substratum have been studied. Out of 31, eight compounds in vitro, five compounds in utero and two in vivo showed adhesion/implantation preventing activity, respectively. The results provide an indication for further exploration in the line of development of anti-adhesive agents. (C) 2001 Published by Elsevier Science Ltd.
