A convenient, inexpensive and effective approach to the synthesis of 2-o-cyanoaryl oxazole derivatives has been developed. Generally, the copper-mediated cyclization/coupling reactions afforded corresponding 2-cyanoaryl oxazoles and oxazolines in moderate

Treatment of propargylamides or propargylamidines with cesium carbonate in DMSO results in the formation of the corresponding oxazoles or imidazoles in good yields. A large variety of substrates with various functional groups are tolerated. DFT study on a model substrate reveals that the reactions proceed via a sequence involving allene formation, intramolecular cyclization, and double-bond isomerization.
Facile, selective, and regiocontrolled synthesis of oxazolines and oxazoles mediated by ZnI2 and FeCl3

An expedient method for a direct approach to the selective and regiocontrolled synthesis of 2-oxazolines and 2-oxazoles mediated by ZnI 2 and FeCl3 is described. A Lewis acid promoted cyclization of acetylenic amide with various func
A simple one-pot synthesis of 2-aryl-5-alkyl-Substituted oxazoles byCs 2CO3-Mediated Reactions of aromatic primary amides with 2,3-dibromopropene

experimental part, p. 2825 - 2827 (2010/03/03)
A simple and efficient method for the synthesis of 2-aryl-5-alkyl- substituted oxazoles has been developed. A series of 2,5-disubstituted oxazoles were synthesized in a single step by Cs2CO3-mediated reactions of aromatic primary amides with 2,3-dibromopr
