an aliphatic substituent. Using a computational approach, 8′-substituted quinolones were identified as potential class 2 and 3 atropisomeric targets with calculated C–N rotational barriers of greater than 20 kcal/mol. These results, along with experimental efforts toward the synthesis of these targets, are reported.
考虑到阻转异构体在不对称催化和药物中的有用性,已对取代的α-(N -2-喹啉基)酮进行了详尽的计算研究。这类叔酰胺是独特的,因为酰胺嵌入在芳族结构中,并且氮带有脂族取代基。使用一种计算方法,将8'-取代的喹诺酮类化合物确定为潜在的2类和3类阻转异构体靶标,其计算的C–N旋转势垒大于20 kcal / mol。报道了这些结果,以及合成这些靶标的实验性努力。
