Ye, Zenghui published the artcilePIDA-Mediated Rearrangement for the Synthesis of Enantiopure Triazolopyridinones, Name: Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is Organic Letters (2020), 22(16), 6464-6467, database is CAplus and MEDLINE.
A tandem oxidative cyclization/1,2-carbon migration of hydrazides for the synthesis of otherwise inaccessible hindered or enantiopure triazolopyridinones has been developed. This protocol exhibits broad substrate scope and can be easily scaled up by continuous flow synthesis under mild conditions. Most importantly, this method demonstrates a rearrangement with retention of configuration and can be readily applied for the late-stage modification of carboxylic-acid-containing pharmaceuticals, amino acids, and natural products to access enantiopure triazolopyridinones.
