该中间体在本合成路线中的序号：(IV)Chiral oxazolidinone intermediate (VI): The oxidation of the terminal double bond of the chiral acyl oxazolidinone (I) with O2 catalyzed by CuCl and PdCl2 in DMF/water gives the ketone (II), which is ketalized with propane-1,3-dithiol (III) and Ts-OH in AcOH to yield the thioketal (IV). Finally, the stereocontrolled acylation of (IV) with propionyl chloride (V) by means of LDA in THF affords the target oxazolidinone intermediate (VI)
