Abstract:
Oxidative C-H amination of chiral sulfamate esters using achiral Rh-carboxylate catalysts, PhI(OAc)(2), and MgO occurs in high yield and with good to excellent diastereocontrol. A number of examples are included to support a proposed transition state model that accounts for the observed stereoinduction. In addition, stereoselective intramolecular aziridination with substituted homoallyl sulfamates is demonstrated and is rationalized through an analogous stereochemical construct. [reaction: see text]

SN2 Reaction: Stereochemistry
If the substrate is an achiral molecule at the α-carbon, the inversion of configuration is not observed.
SN1 Reaction: Stereochemistry
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...
