Yield:28642-64-0 92%
Reaction Conditions:
with N-ethyl-N,N-diisopropylamine;tin(ll) chloride in acetonitrile at 20; for 1 h;Catalytic behavior;Reagent/catalyst;Solvent;
Steps:
1-6 Example 1: The reaction solvent is acetonitrile and the catalyst is anhydrous stannous chloride
Weigh 282 mg of methyl-4,6-benzylidene acetal-α-D-glucoside in 10 ml of acetonitrile, add 265 μl of N,N-diisopropylethylamine and 10 mg of chloride Stannous, stir and mix, then add 140 microliters of benzoyl chloride, react at room temperature for 1 hour, evaporate the solvent,355 mg of pure methyl-2-benzoate-4,6-benzylidene acetal-D-glucoside was separated and dried by column chromatography with a yield of 92%.
