Bifunctional Iminophosphorane-Catalyzed Enantioselective Nitroalkane Addition to Unactivated α,β-Unsaturated Esters [PDF]
Herein we describe the enantioselective conjugate addition of nitroalkanes to unactivated α,β-un-saturated esters, catalyzed by a bifunctional iminophosphorane (BIMP) superbase.

Bifunctional Iminophosphorane Catalyzed Enantioselective Sulfa-Michael Addition to Unactivated α,β-Unsaturated Amides [PDF]
The first metal-free catalytic intermolecular enantioselective sulfa-Michael addition to unactivated α,β- unsaturated amides is described. Consistently high enantiomeric excesses, and yields were obtained over a wide range of alkyl thiol pronucleophiles ...

Access to Spirooxindole-fused Cyclopentanes via Stereoselective Organocascade Reaction using Bifunctional Catalysis [PDF]
The present study reports an asymmetric organocascade reaction of oxindole-derived alkenes with 3-bromo-1-nitropropane efficiently catalyzed by the bifunctional catalyst. Spirooxindole-fused cyclopentanes were produced in moderate-to-good isolated yields

Carbofluorination of Alkenes with gem-Difluorinated Cyclopropanes as Bifunctional Reagents Enabled by Well-Define Rhodium Catalysts [PDF]
Herein, we report a Rh-catalyzed carbofluorination of alkenes using gem-difluorinated cyclopropanes as bifunctional reagents. The developed method tolerates a wide range of alkenes, providing access to secondary, tertiary fluorides and gem-difluorides ...
