Efficient synthesis of benzoylformic acid under mild conditions
Peng,Peng,Li,Rong,Dong,Tai
, p. 78 - 80 (2015)
A new highly efficient synthesis protocol for benzoylformic acid was developed. Of three steps a key unit involved oxidation using clean aqueous hydrogen peroxide and hydrogen bromide systems.

FACILE SYNTHESIS OF α-HYDROXY CARBONYL COMPOUNDS BY ENOLATE OXIDATION WITH DIMETHYLDIOXIRANE
Guertin, Kevin R.,Chan, Tak-Hang
, p. 715 - 718 (1991)
The direct oxidation of enolates with dimethyldioxirane (as a solution in acetone) provides the α-hydroxy derivatives in excellent yield.
Regioselective Hydroperoxylation of Aziridines and Epoxides Only with Aqueous Hydrogen Peroxide
Saleh, SK Abu,Hazra, Atanu,Hajra, Saumen
, p. 391 - 404 (2021/11/01)
A catalyst and organic solvent-free regioselective hydroperoxylation of aziridines and epoxides, including spiroaziridine- and spiroepoxy oxindoles have been explored with commercially available 50% aq. H2O2. This method provides an access to secondary benzylic β-hydroperoxy amines and -alcohols and tertiary 3-hydroperoxy oxindoles. The protocol is also applicable to the less reactive alkyl aziridines. Furthermore, an acid-catalyzed Kornblum-DeLaMare type rearrangement of secondary benzylic hydroperoxide has also been revealed to afford amino- and hydroxyl ketones. (Figure presented.).
Chiral Bidentate Phosphoramidite-Pd Catalyzed Asymmetric Decarboxylative Dipolar Cycloaddition for Multistereogenic Tetrahydrofurans with Cyclic N-Sulfonyl Ketimine Moieties

An asymmetric [3 + 2] cycloaddition of vinyl ethylenecarbonates (VECs) and (E)-3-arylvinyl substituted benzo[d] isothiazole 1,1-dioxides has been developed using the Pd complex of a bidentate phosphoramidite (Me-BIPAM) as the catalyst, providing a wide variety of chiral multistereogenic vinyltetrahydrofurans in good yields with excellent diastereo- and enantioselectivities (up to >20:1 dr, 99% ee).
N-Heterocyclic Carbene Catalyzed Ester Synthesis from Organic Halides through Incorporation of Oxygen Atoms from Air

Oxygenation reactions with molecular oxygen (O2) as the oxygen source provides a green and straightforward strategy for the construction of O-containing compounds. Demonstrated here is a novel N-heterocyclic carbene (NHC) catalyzed oxidative transformation of simple and readily available organic halides into valuable esters through the incorporation of O-atoms from O2. Mechanistic studies prove that the deoxy Breslow intermediate generated in situ is oxidized to a Breslow intermediate for further transformation by this oxidative protocol. This method broadens the field of NHC catalysis and promotes oxygenation reactions with O2.
