Baeyer−Villiger monooxygenases have been tested in the oxidation of racemic benzofused ketones. When employing a single mutant of phenylacetone monooxygenase (M446G PAMO) under the proper reaction conditions, it was possible to achieve 3-substituted 3,4-dihydroisocoumarins with high yields and optical purities through regioselective dynamic kinetic resolution processes.
Baeyer-Villiger单加氧酶已在外消旋苯并稠合的酮的氧化中进行了测试。当在适当的反应条件下使用单个突变体的苯丙酮单加氧酶(M446G PAMO)时,可以通过区域选择性动态动力学拆分过程以高收率和光学纯度获得3-取代的3,4-二氢异香豆素。
