Two conformationally constrained templates have been designed to provide selective inhibitors of the coagulation cascade serine protease, Factor Xa (FXa). The most active inhibitor, 2,7-bis[(Z)-p-amidinobenzylidene)]-3,3,6,6-tetramethylcycloheptanone, exh
The Kharasch reaction revisited: CuX3Li2-catalyzed conjugate addition reactions of Grignard reagents

The conjugate addition of Grignard reagents RMgX to α,β-unsaturated ketones and esters is effectively catalyzed by soluble copper ate-complexes of the type CuX3Li2, e.g.CuI*2LiCl.In the presence of Me3SiCl the corresponding ketone enolsilanes are formed in high yield and selectivity.Diastereoselectivity in the case of chiral ketones is similar to that observed by using stoichiometric amounts of cuprates R2CuLi.Thus CuX3Li2-catalyzed 1,4-additions of Grignard reagents may be an industrially viable process.Keywords: Copper; Magnesium; Lithium; Silicon; Ketone; Enolsilanes
α-Oxosulfines: reactions with alkenes and alkynes

Thiochroman-4-one 1,1-dioxide has been successfully converted into 3-sulfinylthiochroman-4-one 1,1-dioxide and the reactions of this α-oxosulfine with a series of alkenes have been carefully investigated.The α-oxosulfine was found to react as a Diels-Alde
