strategies. Here we present a three-component strategy for the stereoselective enzymatic synthesis of amino-diols and amino-polyols using a diverse set of prochiral aldehydes, hydroxy ketones, and amines as starting materials. We were able to combine biocatalytic aldol reactions, using variants of d-fructose-6-phosphate aldolase (FSA), with reductive aminations catalyzed by IRED-259, identified from a metagenomic
氨基多元醇代表了有吸引力的化学结构单元,但由于不对称官能团的高密度和需要广泛的保护基策略,合成起来可能具有挑战性。在这里,我们提出了一种使用多种前手性醛、羟基酮和胺作为起始材料的立体选择性酶促合成氨基二醇和氨基多元醇的三组分策略。我们能够结合使用 d-果糖-6-磷酸醛缩酶 (FSA) 变体的生物催化醛缩反应与IRED -259 催化的还原胺化反应,从宏基因组文库中鉴定。开发了一种不需要中间体分离的两步法,以避免羰基组分的交叉反应。2 R ,3的立体选择性形成氨基多元醇的R ,4 R对映异构体通过 X 射线晶体学观察和证实。
