An enantioconvergent method for the alkylation of o-disubstituted aryl ketones with racemic secondary alcohols is described. This process is mediated by a commercially available iridium catalyst and proceeds via hydrogen borrowing catalysis. The highly enantioenriched β-substituted ketone products were readily cleaved to a wide range of functional groups via retro-Friedel-Crafts acylation.

Sodium hydride (NaH) is widely used as a Br?nsted base in chemical synthesis and reacts with various Br?nsted acids, whereas it rarely behaves as a reducing reagent through delivery of the hydride to polar π electrophiles. This study presents a series of reduction reactions of nitriles, amides, and imines as enabled by NaH in the presence of LiI or NaI. This remarkably simple protocol endows NaH with unprecedented and unique hydride-donor chemical reactivity.

The intramolecular cyclization of aryl groups to tertiary epoxide position was investigated, and the results were used to test the applicability of Baldwin's rules to this specific class of reactions.As a probe into mechanism of reactions studied earlier, the cyclizations of some meta-substituted 1,2-epoxy-5-phenylpentanes were examined to determine positional selectivities.The data obtained were compared with those of other studies, and comments are made on the reaction mechanism.
