合成路线1
该中间体在本合成路线中的序号：(XXV)Intermediate (XIV) is obtained by selective hydrolysis of dimethyl 1,1-cyclopropanedicarboxylate (XXIII) using NaOH in MeOH/H2O to afford acid-ester (XXIV), which by treatment with ClCO2Et in THF gives the mixed anhydride (XXV). Reduction of carboxylic anhydride (XXV) using NaBH4 in MeOH gives the primary alcohol (XXVI), which is finally activated as mesylate (XIV) by means of MsCl in the presence of DIEA in CH2Cl2 at 0 °C .
