Deprotection regioselective de D-glycals chloroacetyles par l'acetate d'hydrazine
TLDR
In this paper, it was shown that resume chloroacetates are susceptible to regioselective deprotectton by hydraztne acetate, and provide an interesting tool for the synthesis of monomers suitably tailored for the preparation of complex oligosaccharides.About:

Syntheses of a branched heptasaccharide having phytoalexin-elicitor activity
TL;DR: In this paper, a d-glucose heptasaccharide was described as a glucan structure recognized by the soybean when infected by the fungus Phytophthora megasperma f. sp. glycinea and which stimulates the formation of phytoalexins.
