合成路线1
该中间体在本合成路线中的序号：(III)1) By a stepwise conversion of spergualin to DSG in the following sequence: a) Protecting the primary and secondary amines of spergualin with N-(benzyloxycarbonyloxy)suc cinimide to form the N,N'-benzyloxycarbonyl derivative (I); b) protecting the 11-hydroxy group with 3,4-dihydro-2H-pyran to the 11-O tetrahydropyranyl derivative (II); c) converting the 1,5-hydroxy function of (II) to a 1,5-mesylate (III); d) halogenation of (III) with sodium iodide, followed by catalytic hydrogenation, to give 15-deoxy-1-O-tetrahydropyranylspergualin (IV); e) hydrolysis of (IV) with p-toluenesulfonic acid in water to yield 1,5-deoxyspergualin. The overall yield of DSG is 1.8%, based on the amount of spergualin used.
