An efficient iodine-catalyzed synthesis of highly substituted oxazoles is presented. Starting from readily available aryl methyl ketones, β-keto esters, or styrenes, in combination with α-amino acids as amine-containing coupling partners, the corresponding 2-alkyl-5-aryl- substituted oxazoles were obtained in up to 80% yield via a decarboxylative domino reaction.
提出了一种高效的碘催化的高度取代的恶唑合成方法。从容易获得的芳基甲基酮,β-酮酸酯或苯乙烯与α-氨基酸(作为含胺的偶联伙伴)结合开始,可以以高达80%的收率获得相应的2-烷基-5-芳基取代的恶唑通过脱羧多米诺反应。
