Asymmetric induction in the Neber rearrangement of simple ketoxime sulfonates under phase-transfer conditions: experimental evidence for the participation of an anionic pathway.
TL;DR: Enhanced enantioselectivity was observed in the rearrangement of the oxime sulfonate derived from (Z)-1b, and notably, use of mesitylene in place of toluene further increased the enantiOSElectivity to 70% ee.

Chiral Brønsted acid-catalyzed asymmetric trisubstituted aziridine synthesis using α-diazoacyl oxazolidinones.
TL;DR: Chiral N-triflyl phosphoramide-catalyzed reactions of N-α-diazoacyl oxazolidinones and N-Boc imines were developed as a solution to the unmet challenge of stereoselective synthesis of trisubstituted aziridines.

Generation and exploitation of acyclic azomethine imines in chiral Brønsted acid catalysis
TL;DR: Acyclic azomethine imines would be useful prochiral electrophiles in catalytic asymmetric reactions, but their generation often requires harsh conditions, so they are generated under mild conditions in the presence of an axially chiral dicarboxylic acid.
