Highly Enantioselective Catalytic Lactonization at Nonactivated Primary and Secondary g-C–H Bonds

Chiral oxygenated aliphatic moieties are recurrent in biological and pharmaceutically relevant molecules, and constitute one of the most versatile type of functionalities for further elaboration. In this work, Arnau Call, Giorgio Capocasa, Andrea Palone, Laia Vicens, Eric Aparicio, Najoua Choukairi Afailal, Nikos Siakavaras, Maria Eugènia López Saló, Massimo Bietti and Miquel Costas report a protocol

Carboxylic Acid Directed gamma-Lactonization of Unactivated Primary C–H Bonds Catalyzed by Mn Complexes: Application to Stereoselective Natural Product Diversification

Reactions that enable selective functionalization of strong aliphatic C–H bonds open new synthetic paths to rapidly increase molecular complexity and expand chemical space. Particularly valuable are reactions where site-selectivity can be directed toward a specific C–H bond by catalyst control. Herein we describe the catalytic site- and stereoselective ?-lactonization of unactivated primary C–H bonds in

Characterization of a Ferryl Flip in Electronically Tuned Nonheme Complexes. Consequences in Hydrogen Atom Transfer Reactivity

Two oxoiron(IV) isomers ( R2a and R2b) of general formula [FeIV(O)(RPyNMe3)(CH3CN)]2+ are obtained by reaction of their iron(II) precursor with NBu4IO4. The two isomers differ in the position of the oxo ligand, cis and trans to the pyridine donor. The mechanism of isomerization between R2a and R2b has been determined by kinetic and computational analyses
