various functionalized enamides. The developed reaction involves the unprecedented [2,3]-sigmatropic rearrangement of sulfur ylides with the imine motif. Importantly, the method works well with various substituted α-thioesters/-amides/-ketones and substituted N-sulfonyl-1,2,3-triazoles and allows the synthesis of diverse enamide derivatives in good to excellent yields. The reaction was also successfully
由α-硫代酸酯和N-磺酰基-1,2,3-三唑衍生的硫鎓的高效铑催化的Sommelet-Hauser型重排反应已成功完成,用于合成各种官能化的酰胺。发达的反应涉及具有亚胺基序的硫酰化物的前所未有的[2,3]-σ重排。重要的是,该方法与各种取代的α-硫代酯/酰胺/酮和取代的N-磺酰基-1,2,3-三唑类均能很好地起作用,并且可以良好的收率合成各种烯酰胺衍生物。该反应还成功地扩展到由末端炔烃的一锅法合成酰胺。
