Catalytic Enantioselective Intramolecular Aza‐Michael Addition to α,β‐Unsaturated Esters

Angewandte Chemie, EarlyView.
A general method for accessing enantioenriched saturated N‐heterocycles via a catalytic enantioselective intramolecular aza‐Michael reaction to α,β‐unsaturated esters is described. A superbasic bifunctional iminophosphorane (BIMP) catalyst was key to enabling reactivity of the high pKa sulfonamide pronucleophile, whilst delivering good to excellent ...

A Ruthenium‐(Ph‐BPE) Catalyst for Asymmetric Alkynylation of Fluoral: Enantioselection From 1 of 12 Fluxional Stereogenic‐at‐Ruthenium Complexes

Angewandte Chemie International Edition, EarlyView.
The first enantioselective alkynylations of aqueous fluoral are described. These processes are catalyzed by an iodide‐bound ruthenium‐(Ph‐BPE)‐catalyst; an octahedral metal complex that can exist as 12 diastereomeric‐at‐metal isomers. Calculations reveal that 2 of 12 stereoisomeric complexes account for 99.9% of the Boltzmann population and that ...
