合成路线1
该中间体在本合成路线中的序号:(XXXV)Addition of n-propylmagnesium chloride to piperonylonitrile (XXXII), followed by sulfinylation of the intermediate (XXXIII) with menthyl p-toluenesulfinate (XXXIV), furnished the sulfinyl imine (XXXV). Diastereoselective reduction of imine (XXXV) with DIBAL gave the desired sulfinamide (XXXVI). Amine (XVII) was then obtained by mild acidic hydrolysis of sulfinamide (XXXVI).
