A suitable "process window" was identified for the combination of an asymmetric organocatalytic aldol reaction and subsequent biocatalytic reduction in aqueous medium, which thus enabled the enantio- and diastereoselective synthesis of 1,3-diols in a tandem-type, one-pot process. A key feature of this one-pot synthesis is the high 500 mM loading of the aldehyde substrate used as a starting material
确定了一个合适的“工艺窗口”,用于将不对称有机催化羟醛反应和随后在
水性介质中的
生物催化还原相结合,从而能够在串联型一锅法中对映选择性和非对映选择性合成 1,3
-二醇. 这种一锅法合成的一个关键特征是用作起始材料的醛底物负载量高达 500 mM。
