Synthesis of O- and S-glucosides using glucosyl halides and zinc salts

Glycosidation with a Disarmed Glycosyl Iodide: Promotion and Scope

“…We also investigated various “nonheavy” metal salts as promoters, with or without I 2 present. The use of Zn halides with a glucuronyl bromide but with no added I 2 had been reported previously, and a few other metal salts have been used in conjunction with glucosyl bromides . The results for the model reaction, Scheme , are summarized in Table .…”

Synthesis of Glycosylcurcuminoids

“…Similarly, compounds 9 and 10 were converted to diglycosides (11, 13, 15) by method A, and to monoglycosides (12,14,16) by method B (Table 1).…”

“…mp 142°C 16) was dried under reduced pressure at 250°C for 3 h. The dried oxide (0.13 g, 1.8 mmol) was added to acetylacetone (0.25 g, 2.5 mmol) and the mixture was stirred at room temperature for 30 min, and then used directly.…”
