An efficient proline-catalyzed synthesis of 4,5-disubstituted-N-sulfonyl-1,2,3-triazoles has been accomplished from 1,3-dicarbonyl compounds and sulfonyl azides. The developed reaction is suitable for various symmetrical and unsymmetrical 1,3-dicarbonyl compounds, tolerates various functional groups and affords 4,5-disubstituted-N-sulfonyl-1,2,3-triazoles in good yield with excellent regioselectivity
由1,3-二羰基化合物和磺酰基叠氮化物已经完成了有效的脯氨酸催化的4,5-二取代的-N-磺酰基-1,2,3-三唑的合成。所开发的反应适用于各种对称和不对称的1,3-二羰基化合物,耐受各种官能团,并以良好的产率和优异的区域选择性提供了4,5-二取代-N-磺酰基-1,2,3-三唑。铑催化的4,5-二取代-N-磺酰基-1,2,3-三唑的脱氮官能化进一步证明了它们在有机合成中的效用。
