the synthesis of libraries of chiral tris‐ligated cationic platinumcomplexes and their in situ evaluation as asymmetriccarbophilic catalysts in a model domino hydroarylation/cyclization reaction of a 1,6‐enyne was developed. A catalyst‐generation process based on a combination of a monodentate and a bidentate phosphorus ligand allowed the formation of 108 chiralcomplexes. One‐pot screening of the stereoinduction

Disclosed are aspartic protease inhibitors represented by the following Formula: wherein R1 , R2, R3, R4, R5, R6, R7a, R7b and n are as defined herein, or a pharmaceutically acceptable salt thereof, pharmaceutical compositions comprising the same and methods for treating an aspartic protease mediated disorder using the same.
A gold(I)‐catalyzed highly diastereo‐ and enantioselective intermolecular cycloaddition of oxime ethers with nitrones under mild conditions was developed, which provides an facile access to optically pure highly substituted pyrrolo[3,4‐d][1,2]oxazines. The salient features of this reaction include general substrate scope, high efficiency, high enantioselectivity, readily available starting materials
