摘要

Abstract Reaction of ethyl isocyanoacetic acid with sodium hydride in anhydrous benzene, followed by treatment with carboxylic acid chlorides or N-(acyloxy) pyrrolidine-2, 5-diones, gives 5-substituted oxazole-4-carboxylic acid esters. The procedure is applicable to derivatives of various carboxylic acids, including saturated aliphatic, α, β-unsaturated, alicyclic, aromatic, heterocyclic, and N-Boc-protected amino acids.
