A new efficient synthetic route to trans-2,5-dihydro-1H-pyrroles and 1,2-dihydroquinolines that relies on copper(II) triflate-catalyzed intramolecular hydroamination of homoallylic amino alcohols under mild and operationally straightforward conditions is
Epoxy-annulations by reactions of α-amido ketones with vinyl sulfonium salts. Reagent versus substrate control and kinetic resolution
Unthank, Matthew G.,Tavassoli, Bahareh,Aggarwal, Varinder K.
supporting information; experimental part, p. 1501 - 1504 (2009/04/12)
(Chemical Equation Presented) Diphenyl vinyl sulfonium salt and chiral amido-ketones undergo highly diastereoselective epoxy-annulation reactions in good yield. The use of a chiral vinyl sulfonium salt dominates the stereochemical outcome of the annulatio

Conditions for a first oxidative conversion of alkenes into 2-amino ketones are described, which yield racemic products within a direct oxidation pathway and 2-amino ketones with up to 99% enantiomeric excess from the corresponding enantiopure amino alcohols. The Royal Society of Chemistry 2005.
A Lewis acid promoted asymmetric umpolung reaction with chiral N-sulfinyl imines as the electrophiles
Xu, Xin,Liu, Jun-Ying,Chen, Dian-Jun,Timmons, Cody,Li, Guigen
, p. 1805 - 1809 (2007/10/03)
An new asymmetric umpolung reaction has been developed by reacting N-sulfinyl imines with 2-lithio-2-phenyl-1,3-dithiane. The reaction was conducted at between -20 and -25°C in THF in the presence of Et 2AlCl as the Lewis acid promoter. Excelle
