Five mimics of cytochrome P-450 have been prepared and examined as catalysts for the specific hydroxylation of steroids. Reactions occur dictated by the geometries of the complexes, overcoming the intrinsic reactivity of a carbon–carbon double bond and of a secondary carbinol group. In some cases as many as 3000 catalytic turnovers are observed.
已经制备了五种细胞色素P-450的模拟物,并作为类固醇特异性羟基化的催化剂进行了检测。反应的发生取决于配合物的几何形状,克服了碳-碳双键和仲甲醇基团的固有反应性。在某些情况下,观察到多达3000次催化转化。
