TLDR
In this article, the use of C nmr spectra for the determination of configurations of oximes is described, and the problems of quantitative analysis of syn-anti mixtures of oxime by cmr, because of differential T_1 and Overhauser effects, are considered.
Abstract
The use of ^(13)C nmr (cmr) spectra for the determination of configurations of oximes is described. The problems of quantitative analysis of syn-anti mixtures of oximes by cmr, because of differential T_1 and Overhauser effects, are considered. Chemical shifts for the cmr resonances of a number of aldehydes and ketones are reported.

Chiral N‐Acylhydrazones: Versatile Imino Acceptors for Asymmetric Amine Synthesis

TL;DR: In this paper, the chiral N-acylhydrazones were used as versatile imino acceptors for the addition of radicals and nucleophiles, and they achieved high stereoselectivity for addition reactions in the presence of Lewis acids.

A Practical Method for Alcohol Oxidation with Aqueous Hydrogen Peroxide under Organic Solvent- and Halide-Free Conditions.

TL;DR: In this paper, a catalytic system consisting of sodium tungstate and methyltrioctylammonium hydrogensulfate effects oxidation of simple secondary alcohols to ketones using 3-30% H2O2 without any organic solvents.

New 1-aryl-3-(4-arylpiperazin-1-yl)propane derivatives, with dual action at 5-HT1A serotonin receptors and serotonin transporter, as a new class of antidepressants.

TL;DR: 1-aryl-3-(4-arylpiperazin-1-yl)propane derivatives were designed, synthesized, and evaluated for 5-HT reuptake inhibition and 5- HT1A receptor antagonism, which should lead to a rapid and pronounced enhancement in serotoninergic neurotransmission and consequently to a more efficacious treatment of depression.
