合成路线1
该中间体在本合成路线中的序号:(XXIII)The hydroxyl group of (XXXV) was activated by treatment with trichloroacetonitrile to produce the corresponding trichloroacetimidate (XXXVI) as a diastereomeric mixture, which was used without separation. Coupling between imidates (XXXVI) and building block (XXIII) was accomplished by means of trimethylsilyl triflate, producing the disaccharide derivative (XXXVII). The azido groups of (XXXVII) were then reduced employing tin(II)tris-benzenethiolate triethylamine complex to afford diamine (XXXVIII).
