Stepwise benzylic oxygenation via uranyl-photocatalysis
Hu, Deqing,Jiang, Xuefeng
supporting information, p. 124 - 129 (2022/01/19)
Stepwise oxygenation at the benzylic position (1°, 2°, 3°) of aromatic molecules was comprehensively established under ambient conditions via uranyl photocatalysis to produce carboxylic acids, ketones, and alcohols, respectively. The accuracy of the stepwise oxygenation was ensured by the tunability of catalytic activity in uranyl photocatalysis, which was adjusted by solvents and additives demonstrated through Stern–Volmer analysis. Hydrogen atom transfer between the benzylic position and the uranyl catalyst facilitated oxygenation, further confirmed by kinetic studies. Considerably improved efficiency of flow operation demonstrated the potential for industrial synthetic application.

Compounds 4-(oxiran-2-ylmethoxy)benzoic acid (2) and 4-acetoxybenzoic acid (4) are synthesized by a new synthetic route and studied by X-ray crystallography. Compound 2 crystallizes in the monoclinic system, P21/n space group, a = 5.1209(2) A, b = 30.3429(16) A, c = 5.9153(3) A, β = 96.725(3)°, V = 912.81(8) A3, Z = 4. Compound 4 crystallizes in the triclinic system, P-1 space group, a = 7.3400(4) A, b = 8.0819(3) A, c = 15.6548(9) A, α = 85.754(3)°, β = 84.268(2)°, γ = 70.023(3)°, V = 867.63(8) A3, Z = 4. The crystal structure of 2 comprises two crystallographically independent molecules of the compound. In the crystal structures of 2 and 4, pairs of molecules form carboxyl dimers.

Facile synthesis of second-generation dendrons with an orthogonal functional group at the focal point
Cheedarala, Ravi Kumar,Sunkara, Vijaya,Park, Joon Won
experimental part, p. 1966 - 1980 (2009/10/24)
Facile synthesis of second-generation dendrons with an aldehyde, epoxy, or t-Boc group at the focal point and nine carboxylic acid groups at the periphery is reported. The scheme includes a coupling of the first-generation dendrons and a two-step, one-pot reaction that proceeds through a Boc deprotection and in situ conjugation at the focal point.

A series of purine derivatives have been prepared and their in vivo abilities to lower plasma total cholesterol and triglyceride levels, and to elevate high density lipoprotein (HDL) cholesterol levels in hyperlipemic rats have been tested.Some compounds, among which 8-propylthio>adenosine 31, 8--2-oxopropylthio>adenosine 33 and 8--2-hydrazonecarboxamidepropylthio>adenosine 36 appear to be the most interesting, have been found to have both the desired profile of activity and no hepatotoxicity, when administered po at 50, 100 or 300 mg/kg.Compounds 31, 33 and 36, orally tested at the same doses in the 15-d test, lower triglyceride and VLDL/LDL (very low density lipoprotein / low density lipoprotein) cholesterol levels by 10-33percent and 13-46percent, respectively, and increase HDL-associated cholesterol levels by 10-32percent.These molecules have been chosen for further pharmacological and toxicological evaluations. adenosine / purine / cholesterol / triglyceride / hypolipemic agent
