M. Adinolfi et al., Chemoselective cleavage of benzyl ether protecting groups in the presence of benzyloxycarbonyl functions, SYNLETT, (9), 2000, pp. 1277-1278
The modulated lability of benzyl ether and benzyloxy protecting groups towa
rd the NaBrO3/Na2S2O4 reagent can be exploited to remove the former protect
ing groups selectively.
