合成路线1
该中间体在本合成路线中的序号：(XII)3) The reaction of podophyllotoxin (V) with diphenyl chlorophosphate by means of ethyl diisopropylamine and dimethylaminopyridine (DMAP) gives the diphenylphosphoryloxy derivative (VI), which is glycosylated with 4,6-O-ethylidene-2,3-O-bis(2,2,2-trichloroethoxycarbonyl)-beta-D-glycopyranose (VII) by means of BF3/ethyl ether, yielding the protected etoposide derivative (VIII). The cleavage of the protecting groups of the carbohydrate moiety with Zn/acetic acid affords the free etoposide phosphate diphenyl ester (IX), already obtained (compound (III) of scheme 14675903a). The reductive cleavage of (IX) as before gives the free acid (X) (compound (IV) of scheme 14675903a), which is finally treated with NaHCO3. 4) The preceding reaction pathway carried out with dibenzyl chlorophosphate instead of diphenyl chlorophosphate yields compounds (XI), (XII), and finally (XIII), which by hydrogenolysis with H2 over Pd/C affords the free acid (X), already obtained.
