Carbonyl ylide is one of the most important intermediates which can undergo a series of 1,3-dipolar cycloaddition reactions. The C-C heterolysis of oxirane is believed to be the most atom-economic and straightforward way to generate carbonyl ylide. Howeve

The first ring-opening of D-A oxiranes with N-heteroaromatics in a chemoselective C-C bond cleavage manner was achieved. In the presence of 5 mol% of Y(OTf)3 as the catalyst, diverse N-heteroaromatics, including benzotriazoles, purines, substituted benzim

The catalytic asymmetric epoxidation of 2-arylidene-1,3-diketones using aqueous 30% H2O2 as oxidant has been successfully realized by a N,N'-dioxide-scandium(III) triflate [Sc(OTf)3] complex, giving the corresponding products in moderate to good yields (up to 85%) with excellent enantioselectivities (up to 99% ee) under mild reaction conditions without extra additives.
Nickel-catalyzed annulation of donor-acceptor oxiranes with imines: Diastereoselective access to highly substituted 2,4-trans-oxazolidines

An efficient approach for the synthesis of highly substituted 2,4-trans-oxazolidines has been achieved by means of nickel(II) chlorate hexahydrate [Ni (ClO4)2·6H2O]-catalyzed [3+2] dipolar cycloaddition reactions of donor-
Asymmetric epoxidation of 2-arylidene-1,3-diketones: Facile access to synthetically useful epoxides
Russo, Alessio,Lattanzi, Alessandra
experimental part, p. 2633 - 2638 (2010/07/16)
In this article the first enantioselective epoxidation reaction of acyclic and cyclic 2-arylidene-1,3-diketones is reported. Easily accessible or commercially available α,α-diaryl prolinols as the organocatalysts in the presence of tert-butyl hydroperoxid
