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.).

In this paper, we designed and synthesized a new type of cyclic carbonates, allenylethylene carbonates (AECs). With AECs as reactive precursors, we developed palladium-catalyzed (3+3) annulation of AECs with nitrile oxides. Various AECs worked well in this reaction under mild reaction conditions. A variety of 5,6-dihydro-1,4,2-dioxazine derivatives with allenyl quaternary stereocenters can be accessed in a facile manner in high yields (≤98%).

Chlorine is the 20th most abundant element on the earth compared to bromine, iodine, and fluorine, a sulfonimide reagent, N-chloro-N-(phenylsulfonyl)benzenesulfonamide (NCBSI) was identified as a mild and selective oxidant. Without activation, the reagent was proved to oxidize primary and secondary alcohols as well as their symmetrical and mixed ethers to corresponding aldehydes and ketones. With recoverable PS-TEMPO catalyst, selective oxidation over chlorination of primary and secondary alcohols and their ethers with electron-donating substituents was achieved. The reagent precursor of NCBSI was recovered quantitatively and can be reused for synthesizing NCBSI.
