Nitrogen chirality: Potent new ACAT inhibitors with seven‐membered‐ring benzolactams as the core structures were first prepared, and the axial chirality recognized by the enzyme was clarified (e.g., 1; see scheme). The chirality at the axis (aS) of 1 controls the conformation of the entire lactam ring, causing the N5‐CH3 to arrange in a pseudo‐equatorial position (i.e., the amine at N5 is a chiral center
氮手性:首先制备了以七元环苯并内酰胺为核心结构的强力新型ACAT抑制剂,并阐明了酶识别的轴向手性(例如1;参见方案)。轴(a S)为1的手性控制整个内酰胺环的构象,从而使N 5–CH 3排列在假赤道位置(即,N 5处的胺与S的手性中心‐配置)既处于晶体状态又处于溶液状态。
