Surprisingly, mechanochemical enzymatic transformations have only scarcely been studied until now. Here, we demonstrate the use of lipase B from Candida antarctica (CALB) in acylative kinetic resolutions of secondary alcohols in mixer and planetary mills. Despite the mechanical stress caused by the high‐speed ball milling, the biocatalyst proved highly effective, stable, and, in part, recyclable under the
机械合成是一种有价值的技术,为制备有机,无机和有机金属产品提供了有吸引力的替代方法。出人意料的是,到目前为止,几乎没有研究过机械化学酶促转化。在这里,我们证明了来自南极假丝酵母(CALB)的脂肪酶B在混合机和行星磨机中仲醇的酰基化动力学拆分中的用途。尽管高速球磨产生了机械应力,但该生物催化剂被证明在所施加的机械化学条件下非常有效,稳定并且可以部分回收。
