Pseudomonas cepacia lipase catalyzes the acetylation in organic solvent of dihydroxyaldehydes and ketones using vinyl acetate as acyl donor. The method is completely regioselective and allows to obtain partially acetylated compounds different from those obtained by enzymic hydrolysis of polyacetoxy arylaldehydes and ketones.
假单胞菌洋葱脂肪酶在乙酸乙烯酯作为酰基供体的情况下催化二羟基醛和酮在有机溶剂中的乙酰化。该方法是完全区域选择性的,并允许获得部分乙酰化的化合物,该化合物与通过酶水解聚乙酰氧基芳基醛和酮获得的化合物不同。
