Scandium triflate-catalyzed 1,3-dipolar cycloaddition of aziridines with alkenes ☆

Abstract Phenyl aziridines undergo 1,3-dipolar cycloaddition efficiently with olefins such as cyclic enol ethers and allyltrimethylsilane in the presence of a catalytic amount of Sc(OTf)3 at ambient temperature to afford the corresponding pyrrolidine derivatives in high yields with high regioselectivity.

Ceric(IV) ammonium nitrate-catalyzed glycosidation of glycals: a facile synthesis of 2,3-unsaturated glycosides

Glycosidation of glycals with alcohols in the presence of a catalytic amount of ceric(IV) ammonium nitrate under neutral conditions proceeds smoothly in refluxing acetonitrile to afford the corresponding 2,3-unsaturated glycosides in excellent yields.

INDIUM(III) CHLORIDE CATALYZED EFFICIENT CONVERSION OF CARBONYL COMPOUNDS TO 1,3-DITHIOACETALS

ABSTRACT Several aldehydes and ketones were efficiently converted into their corresponding dithioacetals and 1,3-dithianes in high yields using catalytic amount of indium(III) chloride in dichloromethane.
