isosteres of the amide bond. Little is known about the rates of hydrolysis for aliphatic sulfinamides or the mechanism of hydrolysis. In this Letter, we show that sulfinamides hydrolyse by predominantly a non-specific acid/base catalysis with phosphate buffer but by varying the buffer concentration, it was possible to determine the hydrolysis rates of a range of sulfinamides with water through non-linear
亚磺酰胺在对映选择性合成中很重要,它是蛋白质的罕见翻译后修饰,也是酰胺键的等排物。关于脂族亚磺酰胺的水解速率或水解机理知之甚少。在这封信中,我们证明了亚磺酰胺主要通过磷酸盐缓冲液的非特异性酸/碱催化水解,但是通过改变缓冲液浓度,可以通过非线性最小二乘法确定一定范围的亚磺酰胺在水中的水解速率。回归。
