decarboxylase (PDC) from Saccharomyces cerevisiae provide different CC bond forming possibilities of α,β-unsaturated aldehydes with aliphatic and aromatic aldehydes. Structure elucidation and determination of the absolute configuration of the products, which were obtained with high regio- and stereoselectivity were carried out. Selective 1,2-reactivity with yields of 75% and >98% ee, for one single isomer
酶裂解酶的
苯甲醛(BAL)从荧光假单胞菌,
苯甲酰甲酸脱羧酶(BFD)恶臭假单胞菌从和
丙酮酸脱羧酶(
PDC)酿酒酵母提供不同的CC键形成与脂肪族和
芳香族醛的α可能性,β不饱和醛。进行了结构阐明和确定了产物的绝对构型,这些产物具有很高的区域选择性和立体选择性。通过选择合适的酶和合适的底物,获得了一种单一异构体(A)的选择性1,2反应性,产率为75%ee和> 98%ee。通过改变酶或底物的区域异构羟基酮可以获得ee高达99%以上的C。通过应用不同的依赖ThDP的酶作为催化剂,可以大大促进这些新的手性结构单元在
天然产物或
生物活性物质合成中的应用。
