Radical-polarcrossover hydrofunctionalizations of tertiary allylic alcohols are described. Depending on the structure of the catalyst, corresponding epoxides or semipinacol rearrangement products are selectively obtained in good yields. Experimental evidence points to the participation of alkylcobalt complexes as electrophilic intermediates.

A nonconventional approach to the preparation of morphinans has been applied to the total synthesis of thebainone-A and β-thebainone-A. Noteworthy features of this synthesis are the regiospecificity of the Diels-Alder reaction to form 9 and of the enolization-hydroxylation of 11, the unusual aromatization of 14 as well as the selectivity of the intramolecular Michael addition of the of the anine to
Provided are compounds that target the lanthionine synthetase C-like protein 2 pathway. The compounds can be used to treat a number of conditions, including infectious disease, autoimmune disease, diabetes, and a chronic inflammatory disease.

Asymmetric intramolecular hydrofunctionalization of tertiary allylic alcohols is described. This metal hydride-mediated catalytic radical-polar crossover reaction delivers corresponding epoxides in good to high enantioselectivity and constitutes the first example of asymmetric hydrogen atom transfer-initiated process. A series of modified cobalt salen complexes has proven optimal for achieving good
