该中间体在本合成路线中的序号：(XVIII)

In a related procedure, epoxy carboxylic acid (XVII) was either obtained by basic hydrolysis of ethyl ester (XV) or by hydrogenolysis of benzyl ester (XVI). Alternatively, acid (XVII) was isolated as the dimethylaminopyridinium salt. Coupling of (XVII) with protected taxane (XI) provided ester (XVIII). Then, epoxide opening in (XVIII) with either NaN3 or Bu3SnN3 and ZnI2 gave azide (XIX). Subsequent hydrogenation of (XIX) produced amine (XX), which was treated with Boc2O to yield intermediate (XIII).
