An aluminum carbenoid is the efficient cyclopropanation reagent for the transformation of 2-alkenyl amines into cyclopropyl amines. The addition of iodine facilitates the cyclopropanation of poorly reactive 2-alkenyl amines.

The palladium-catalyzed reaction between aryl or perfluoro-alkyl iodides and tertiary allylicamines provides a practical route to 3-aryl- or 3-perfluoroalkyl-allylic amines. The outcome of the arylation of tertiary allylicamines can be affected by a change of solvent.

Disclosed herein are vinyl-bromides, vinyl-boronic acids and vinyl-boronic acid derivatives useful as synthetic intermediates for the preparation of therapeutic agents. Also disclosed are methods of synthesis of vinyl-bromides, vinyl-boronic acids and vinyl-boronic acid derivatives.
Heterocyclic compounds derived from benzotriazine, triazines, triazoles and oxadiazoles are disclosed. The methods of synthesis and of use of such heterocyclic compounds are also provided.
amination of olefins with secondary alkyl amines to afford allylic amines, eliminating the need for oxidants. This method is compatible with a broad scope of olefins and can be extended to achieve a site- and diastereoselective amination of terpenes. Mechanistic studies disclose that the reaction proceeds via a cobaloxime-promoted hydrogen atom transfer pathway to afford the product that results from cleavage
