The synthesis of N-tosylbenzopyran[2]benzazepinone 2 using a simple protocol for assembly of an azepine ring on the xanthene skeleton is described. Formation of the CC bond between C9 of the xanthen-9-ol 7 and the β-C of N-tosyl aminoacetaldehyde dimethyl acetal leads to 10, which upon treatment with formaldehyde undergoes ring closure.
描述了使用简单的方案在assembly吨骨架上组装氮杂环庚烷环合成N-甲苯磺酰基苯并吡喃[2]苯并ze庚酮2的方法。黄原9-9-ol 7的C9与N-甲苯磺酰基氨基乙醛二甲基乙缩醛的β-C之间的CC键形成10,在用甲醛处理后会发生闭环。
