Electrochemical two-electron oxygen reduction reaction (ORR) induced aerobic oxidation of α-diazoesters

Electrochemical oxygen reduction reaction (ORR) is a powerful tool for introducing oxygen functional groups in synthetic chemistry. However, compared with the well-developed one-electron oxygen reduction process, the applications of two-electron oxygen re

NEGATIVE ALLOSTERIC MODULATION OF GLUN3-CONTAINING N-METHYL-D-ASPARTATE RECEPTORS

Disclosed are negative allosteric modulators of GluN3-containing NMDA receptors. In general, these compounds are highly selective for GluN3 (such as GluN3A and/or GluN3B) over GluN1 and/or GluN2. They can function as non-competitive antagonists with activity that is independent of membrane potential, glycine concentration, and extracellular pH. Also disclosed are pharmaceutical formulations of the negative allosteric modulators. These compounds can be used to enhance synaptic function and/or treating a neurological condition or disorder. Exemplary neurological conditions or disorders include, but are not limited to, major mental disorders, conditions that involve basal ganglia or altered dopamine, substance abuse/addiction or predisposition to substance abuse/addiction, pain disorders, developmental delay or situations with impaired learning, memory, and/or cognition, acute neuronal or glial injuries, and circuit disorders.

Ambient and aerobic carbon-carbon bond cleavage toward α-ketoester synthesis by transition-metal-free photocatalysis

The α-oxoesterification of the CC double bond in readily available enaminones enabling efficient synthesis of α-ketoesters is developed. The reactions showing general tolerance to the reactions of primary and secondary alcohols proceed well under air via Rose Bengal (RB)-based photocatalysis. Particularly, this mild synthetic method has been discovered to tolerate various polyhydroxylated substrates such as phenolic alcohol, diols and triols with an excellent selectivity of mono-oxoesterification. What is more noteworthy is that α-ketoester functionalized 16-dehydropregnenolone acetate resulting from the elaboration on a natural product has been obtained practically.

Copper-catalyzed Pummerer type reaction of α-thio aryl/heteroarylacetates: Synthesis of aryl/heteroaryl α-keto esters

A copper catalyzed Pummerer type reaction of α-thio aryl/heteroarylacetates is described for the first time. This transformation represents a new route to synthesize α-keto esters, which are important intermediates for pharmaceuticals and organic synthesis. The reaction proceeds via in situ generation of a thionium ion that undergoes hydrolysis to furnish α-keto esters in synthetically viable yields (up to 82%).

Highly homogeneous stereocontrolled construction of quaternary hydroxyesters by addition of dimethylzinc to α-ketoesters promoted by chiral perhydrobenzoxazines and B(OEt)3

A highly efficient enantioselective addition of Me2Zn to α-ketoesters, assisted by a chiral perhydro-1,3-benzoxazine ligand, is described. This novel catalytic system offers homogeneous elevated enantioselectivities in the preparation of α-hydroxyesters that bear a quaternary stereocenter, with a minor dependence on electronic and steric effects when aromatic, heteroaromatic, or aliphatic α-ketoesters are employed. The catalyst can be recovered and reused without loss of activity.

Reliable and versatile synthesis of 2-aryl-substituted cinnamic acid esters

2-Aryl-substituted phosphono acetates can be readily synthesized by a four-step sequence from the respective arenes. Succeeding Horner-Wadsworth- Emmons olefinations provide stereoselectively the 2-aryl cinnamic acid esters even when sensitive moieties are involved. Georg Thieme Verlag Stuttgart.
