A novel synthetic strategy is presented in which the heteroaryl[(trimethylsilyl)oxy]acetonitrile intermediate 3 is utilized either as a homologation or reverse-polarity synthon for convenient entry into its corresponding α-hydroxy- and α-ketoarylalkanoate 4 and 6, respectively. Further functionalization, including a stereo-selective oximation procedure, is described.
提出了一种新颖的合成策略,其中杂芳基[(三甲基甲硅烷基)氧基]乙腈中间体3被用作同系物或反极性合成子,以方便地分别进入其相应的α-羟基-和α-酮基芳基链烷酸酯4和6。描述了进一步的功能化,包括立体选择性肟化方法。
