Catalytic syntheses of N-heterocyclic ynones and ynediones by in situ activation of carboxylic acids with oxalyl chloride

Breaking the bottleneck: α-Keto carboxylic acids and N-heterocyclic carboxylic acids are activated in situ with oxalyl chloride then catalytically alkynylated to give ynediones and N-heterocyclic ynones efficiently in a one-pot fashion. 5-Acylpyrazoles and 2-phenylaminopyrimidines, potentially interesting for pharmaceutical applications, are readily synthesized in concise one-pot, three-component syntheses.

One-pot activation-alkynylation-cyclization synthesis of 1,5-diacyl-5-hydroxypyrazolines in a consecutive three-component fashion

A consecutive three-component activation-alkynylation-cyclization reaction of (hetero)aryl glyoxylic acids, oxalyl chloride, arylacetylenes, and hydrazides efficiently forms 1,5-diacyl-5-hydroxypyrazolines in moderate to good yields. The structures were unambiguously corroborated by comprehensive NMR spectroscopy and X-ray structure analyses of selected derivatives.
Solvatochromic fluorescent 2-substituted 3-ethynyl quinoxalines: Four-component synthesis, photophysical properties, and electronic structure
Gers, Charlotte F.,Nordmann, Jan,Kumru, Ceyda,Frank, Walter,Müller, Thomas J. J.
, p. 3296 - 3310 (2014/05/06)
2-Substituted 3-ethynylquinoxalines can be rapidly synthesized in generally excellent yields by a consecutive four-component synthesis starting from electron-rich π-nucleophiles, oxalyl chloride, terminal alkynes, and 1,2-diaminoarenes. The title compound
