合成路线1
该中间体在本合成路线中的序号：(XXIX)The condensation of anhydro imidazolide (XIII) with the substituted hydrazine (XXIII) generated the cyclic carbamate (XXVII). After acidic cleavage of the cladinose moiety, the resultant ketone (XXVIII) was converted to the O-methyl oxime (XXIX). The title compound was then obtained by Swern oxidation of (XXIX) followed by basic hydrolysis.
