Electronic probing of ketone catalysts for asymmetric epoxidation. Search for more robust catalysts

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.

Pseudoamide-Type Pyrrolidine and Pyrrolizidine Glycomimetics and Their Inhibitory Activities against Glycosidases

Coupling reaction of (2R,3R,4R,5R)-2,5-hydroxy-methyl-3,4-dihydroxypyrrolidine (DMDP) with isothiocyanates afforded the corresponding thiourea adducts, which were transformed into isourea-type bicyclic oxapyrrolizidine glycomimetics by mercury(II) oxide-assisted intramolecular sulfur displacement. Cyclic carbamate and thiocarbamate analogues were also prepared by direct carbonylation or thiocarbonylation of DMDP. Evaluation of the glycosidase inhibitory properties demonstrated that remarkable specificities in enzyme inhibition can be achieved upon modifications on the pseudoaglyconic side chain and on the nature of the sp2-hybridized endocyclic ring nitrogen.
