Lekkala, Chinnari published the artcileCopper-Catalyzed One-Pot Synthesis of 2,5-Disubstituted 1,3,4-Oxadiazoles from Arylacetic Acids and Hydrazides via Dual Oxidation, HPLC of Formula: 104-01-8, the main research area is arylacetic acid hydrazide cuprous chloride catalyst oxidative decarboxylation heterocyclization; phenyl oxadiazole preparation.
A simple and efficient protocol was developed to access sym. and unsym. 2,5-disubstituted 1,3,4-oxadiazoles from arylacetic acids and hydrazides via copper-catalyzed dual oxidation under an oxygen atm. Oxidative decarboxylation of arylacetic acids and oxidative functionalization of the imine C-H bond were the key steps. This was the first example of the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles through dual oxidation in one-pot. Avoidance of the expensive ligand and high yield of the products were advantageous features of the developed method.
ACS Omega published new progress about C-H bond activation. 104-01-8 belongs to class isoquinoline, name is 4-Methoxyphenylacetic acid, and the molecular formula is C9H10O3, HPLC of Formula: 104-01-8.
