The first total synthesis of (−)-benzomalvin A 1, which possesses quinazolin-4(3H)-one moiety and 1,4-benzodiazepin-5-one moiety, was described. Both of 6- and 7-membered ring skeletons were efficiently constructed by intramolecular aza-Wittig reactions as the key reactions.
(−)-benzomalvin A 1 的首次全合成被报道,该化合物具有喹唉-4(3H)-酮部分和1,4-苯二氮杂革-5-酮部分。通过分子内的氮杂Wittig反应高效构建了6元环和7元环骨架,这些反应被作为关键反应。
