Under very mild conditions, the Rhodococcus sp. AJ270-catalysed biotransformation of arylglycine nitriles 1, prepared easily from the reaction of substituted benzaldehydes, ammonium chloride and potassium cyanide, proceeded efficiently to produce optically active d-arylglycine amides 2 and l-arylglycines 3 in excellent yields with enantiomeric excesses higher than 99%.
在非常温和的条件下,红球菌属。由取代的苯甲醛,氯化铵和氰化钾的反应轻松制备的AJ270催化的芳基甘氨酸腈1的生物转化可有效地以优异的收率生产光学活性的d-芳基甘氨酸酰胺2和l-芳基甘氨酸3,对映体过量率高于99% 。
