developed a novel and convenient stereoselective path for the preparation of pyrrolo-1,5-benzoxazepinones (PBOs). This innovative route envisaged the employment of (−)-menthol as convenient chiral auxiliary and a key SNAr for the stereoselective preparation of a tertiary aryl–alkyl ether. As a further advancement, we exploited this newly conceived synthetic route for the preparation of 2-substituted PBO analogues
我们开发了一种新颖且方便的立体选择路径,用于制备吡咯并-1,5-苯并恶嗪酮(PBO)。这一创新途径设想了使用(-)-薄荷醇作为方便的手性助剂和关键的S N Ar,用于立体选择性地制备叔芳基-烷基醚。作为进一步的进步,我们利用这种新构想的合成路线来制备2取代的PBO类似物,以对其自身进行生物学评估或获得各种其他功能化选择。
