We report here the silylation of α,β-unsaturated acceptors in water at room temperature using a copper catalyst. A broad substrate scope, including chalcone derivatives, esters, nitrile, and dienones, has been explored. In all cases, the reaction p

A heterogeneous iridium-complex-catalyzed N-O-cleaving rearrangement/cyclization of 2,3-dihydroisoxazoles with alkenes has been developed. It provides divergent access to multiple substituted pyrrolidines, pyrroles, and carbazoles. The iridium cataly

A metal-free aerobic autoxidative nitrooxylation of alkenyl oximes mediated by tert-butyl nitrite is described. Molecular oxygen is used as the oxidizing reagent, avoiding use of organic trapping reagents such as 2,2,6,6-tetramethylpiperidine 1-oxyl

A zinc diiodide (ZnI2)-mediated direct synthesis of 2,3-dihydroisoxazoles via a [3+2] cycloaddition reaction of the nitrones and non-electron-deficient terminal alkynes has been developed. This method was applied in the formal synthesis of HPA-12 and

Oxychlorination of alkenyl oximes is harder compared to the analogous oxybromination or oxyiodination because of the difficulty associated with the formation of chlorine cations or radicals. A transition-metal-free oxychlorination of alkenyl oximes h

Highly functionalized indoles and indolones were prepared via selectivity-switchable mono- or diolefinations. The Julia olefination of the products followed by a Bronsted acid-prompted cyclization afforded indolones, whereas the indoles were obtained

A base-catalyzed/promoted transition-metal-free direct alkylation of amines with alcohols has been developed, giving the desired amines in generally high yields from either aromatic or aliphatic alcohols. On the basis of the (1)H NMR and in situ IR (

Sodium borohydride reduction in aprotic solvents has always been an unsolved problem. In this work a ion-pair-catalyzed sodium borohydride reduction in aprotic solvents was kinetically and mechanistically studied. Finally sodium borohydride reduction
