C2-symmetric cyclic selenium-catalyzed enantioselective bromoaminocyclization

A catalytic asymmetric bromocyclization of trisubstituted olefinic amides that uses a C2-symmetric mannitol-derived cyclic selenium catalyst and a stoichiometric amount of N-bromophthalimide is reported. The resulting enantioenriched pyrrolidine products, which contain two stereogenic centers, can undergo rearrangement to yield 2,3-disubstituted piperidines with excellent diastereoselectivity and enantiospecificity.

Vinylogous Wolff Rearrangement. 4. General Reaction of β,γ-Unsaturated α'-Diazo Ketones

The preparation and vinylogous Wolff rearrangement (VWR) of some 21 acyclic and monocyclic β,γ-unsaturated α'-diazo ketones are described.The resulting γ,δ-unsaturated esters are summarized in Tables I-VI.The rearrangement is promoted by CuSO4, Cu(AcAc)2,
