The efficient generation of novel, N-linked benzamidines resulting from a regiospecific rearrangement of quinazolinones is described. This methodology study explored reaction parameters including the effect of changing solvent and temperature, as well as varying electronic substituents on the structural core. The transformation was extensively optimized in terms of reaction conditions and scope, resulting
描述了由喹唑啉酮的区域特异性重排产生的新型N-联苯甲idine的有效生成。该方法学研究探索了反应参数,包括变化的溶剂和温度的影响以及结构核心上变化的电子取代基。就反应条件和反应范围而言,对转化进行了广泛的优化,从而形成了始终如一地以高收率提供各种功能化am的方案。该方法可实现以前无法实现的区域结构衍生化,并且多步过程也简化为可伸缩的五步序列,可有效地从N中获得药理学上独特的(E)-苯甲酰胺基s-BOC保护的γ-和δ-氨基酸。
