An unprecedented acetal migration was observed when 1,2:4,5-di-O-isopropylidene-d-fructose was treated with various acyl chlorides and 1,4-diaza-bicyclo[2.2.2]octane (DABCO). 2,3:4,5-Di-O-isopropylidene-d-fructose derivatives were isolated as the only pro

Equation presented Ketones with a fused oxazolidinone were synthesized and investigated to determine the electronic effect of the substituents at α-positions of ketone catalysts on the Baeyer-Villiger oxidation and catalytic properties for asymmetric epoxidation. These new ketones give high yields and ee's with only 1 5 mol % catalyst. The current studies further show that the electronic effect is very important for the kitone-catalyzed epoxidation.
