An, Ju Hyeon; Kim, Kyu Dong; Lee, Jun Hee published their research in Journal of Organic Chemistry in 2021. The article was titled 《Highly Chemoselective Deoxygenation Of N-Heterocyclic N-Oxides Using Hantzsch Esters As Mild Reducing Agents》.COA of Formula: C3H6O2 The article contains the following contents:
A highly chemoselective room-temperature deoxygenation method applicable to various functionalized N-heterocyclic N-oxides via visible light-mediated metallaphotoredox catalysis using Hantzsch esters as the sole stoichiometric reductant to afford deoxygenated N-heterocycles I [R = 6-OMe, 6-Cl, 2-Ph, etc.], II [R1 = H, 5-Br; X = CH, N] and III [R2 = 3-Ph, 2,6-Cl2, pyridin-2-yl, etc.] were reported. Despite the feasibility of catalyst-free conditions, most of these deoxygenations could be completed within a few minutes using only a tiny amount of a catalyst. This technol. also allowed for multigram-scale reactions even with an extremely low catalyst loading of 0.01 mol %. The scope of this scalable and operationally convenient protocol encompassed a wide range of functional groups, such as amides, carbamates, esters, ketones, nitrile groups, nitro groups and halogens, which provided access to the corresponding compounds I, II and III in good to excellent yields (an average of an 86.8% yield for a total of 45 examples). In the experiment, the researchers used Oxetan-3-ol(cas: 7748-36-9COA of Formula: C3H6O2)
Oxetan-3-ol(cas: 7748-36-9) is used as a reagent in the synthesis of 5-fluoro-4,6-dialkoxypyrimidine GPR119 agonists. It is also used as a reagent in the synthesis of cyclic sulfone hydroxyethylamines as potent and selective β-site APP-cleaving enzyme 1 (BACE1) inhibitors.COA of Formula: C3H6O2
