Broad-Scope Amination of Aryl Sulfamates Catalyzed by a Palladium Phosphine Complex [PDF]

ACS Catalysis, 2023
Among phenol-derived electrophiles, aryl sulfamates are attractive substrates since they can be employed as directing groups for C–H functionalization prior to catalysis. However, their use in C–N coupling is limited only to Ni catalysis.

Covalent Tethers for Precise Amino Alcohol Syntheses: Ring Opening of Epoxides by Pendant Sulfamates and Sulfamides. [PDF]

Org Lett, 2023
We describe the development of the first ring opening of epoxides using pendant sulfamates and sulfamides. These reactions are promoted by a base and proceed under mild conditions to afford oxathiazinanes and cyclic sulfamides with excellent ...

Ring Opening of Aziridines by Pendant Sulfamates Allows for Regioselective and Stereospecific Preparation of Vicinal Diamines. [PDF]

J Org Chem, 2023
The ring-opening of aziridines by pendant sulfamates is a viable strategy for the rapid preparation of vicinal diamines. Our reaction is compatible with both di-substituted cis and trans aziridines; unsubstituted, N-alkyl, and N-aryl sulfamates engage ...

Silver Catalyzed Site-Selective C(sp³)−H Bond Amination of Secondary over Primary C(sp³)−H Bonds [PDF]

Molecules, 2022
Sulfamates are widespread in numerous pharmacologically active molecules. In this paper, Silver/Bathophenanthroline catalyzed the intramolecular selective amination of primary C(sp3)−H bonds and secondary C(sp3)−H bonds of sulfamate esters, to produce ...
