enantioselective Michael addition using water as both nucleophile and solvent has to date proved beyond the ability of synthetic chemists. Herein, the direct, enantioselective Michael addition of water in water to prepare important β‐hydroxy carbonyl compounds using whole cells of Rhodococcus strains is described. Good yields and excellent enantioselectivities were achieved with this method. Deuterium
迄今为止,已证明使用水作为亲核试剂和溶剂的对映选择性迈克尔加成超出了合成化学家的能力。在此,描述了使用红球菌菌株的全细胞,在水中直接、对映选择性迈克尔加成水来制备重要的β-羟基羰基化合物。该方法获得了良好的产率和优异的对映选择性。氘标记研究表明迈克尔水合酶仅通过反立体化学催化水的添加。
