[reaction: see text] Quinones bearing electron-withdrawing groups can serve as useful precursors to furobenzofuran ring systems through their reaction with 2,3-dihydrofuran. Formal racemic and stereoselective syntheses of the fungal metabolite aflatoxin B(2) are described that utilize this approach to construct the tricyclic ABC-ring core of the molecule.
[反应:见正文]带有吸电子基团的醌可通过与2,3-二氢呋喃的反应用作呋喃苯并呋喃环系统的有用前体。形式外消旋和立体选择性合成的真菌代谢产物黄曲霉毒素B(2),利用这种方法来构建分子的三环ABC环核心。
