合成路线1
该中间体在本合成路线中的序号：(IV)This compound can be obtained by two related ways: 1) The reaction of vinblastine (I) with anhydrous hydrazine in hot ethanol gives 4-deacetylvinblastine-23-acid hydrazide (II), which by reaction with HCl and NaNO2 in cool methanol - water is converted into the corresponding azide (III). Finally, this compound is condensed with L-tryptophan ethyl ester (IV) in dichloromethane. 2) The hydrolysis of vinblastine (I) with NaOH in refluxing ethanol gives 4-deacetylvinblastoic acid (V), which is condensed with L-tryptophan ethyl ester (IV) by means of isobutyl chloroformate (VI) and N-ethylmorpholine in DMF to afford the 4-O-(isobutoxycarbonyl) derivative (VII). Finally, this compound is partially hydrolyzed with KOH in ethanol.
