concept was successfully demonstrated through the enantiodivergent synthesis of 12 structurally diverse (S)- and (R)-2-biarylpropanoic acids (94–97% ee; up to >99% conversion) from easily available aryl alkenes by engineering epoxidation–isomerization–oxidation biocascades containing enantio-complementary enzymes and combining with Pd-catalyzedcross-coupling. The enzyme-chemical strategy was extended
化学酶反应在不对称合成方面受到了极大的关注,但大多数报道的系统仅使用一步或两步酶反应进行相对简单的功能化,并且基于化学酶序列,该序列受到酶底物范围的限制。在此,我们报告了“多酶级联─化学催化”概念,通过酶-化学序列,通过整合多步生物级联引入功能性和对映选择性,对简单底物进行复杂的不对称功能化,并通过强大的化学催化使产品范围多样化。通过环氧化-异构化工程,从容易获得的芳基烯烃中对映异构合成12 种结构不同的 ( S )- 和 ( R )-2-联芳基丙酸(94–97% ee;高达 >99% 转化率) ,成功证明了这一概念–含有对映体互补酶并与 Pd 催化交叉偶联结合的氧化生物级联。酶化学策略扩展到 NSAID 药物 ( S )-氟比洛芬、( S )-酮洛芬和联苯乙酸的高产合成。这一概念能够简化每种类型的催化剂单独或化学酶序列无法实现的合成路线。
