antifungal activities. In order to develop a versatile method to access these substituted triazoles, we have explored the generation of (1H-1,2,4-triazol-1-yl)methyl carbanion and its condensation with carbonyl compounds. Due to a careful choice of a suitable anion precursor (tributylstannyl group) or a stabilizing anion group (a thiophenyl or a phenylsulfoxide group), a wide range of aldehydes and ketones
2-(1H-1,2,4-triazol-1-yl) 乙醇由于其除草和抗真菌活性而在农业和药物化学中受到了极大的关注。为了开发一种通用的方法来获取这些取代的三唑,我们探索了 (1H-1,2,4-triazol-1-yl) 甲基碳负离子的生成及其与羰基化合物的缩合。由于仔细选择了合适的阴离子前体(三丁基甲锡烷基)或稳定的阴离子基团(苯硫基或苯亚砜基团),广泛的醛和酮与碳负离子发生反应,导致大量不同的 2-(1H- 1,2,4-三唑-1-基)乙醇产率良好。
