Biocompatible: A modular chemoenzymatic synthesis (see scheme) based on asymmetric organo‐ and biocatalytic reaction sequences allows the sequential construction of both stereogenic centers of 1,3‐diols and leads to all four possible stereoisomers in enantiomerically pure form. The biocompatibility of the organocatalytic aldol reaction allows its direct use in the subsequent enzymatic reduction without
生物相容性:基于不对称有机和生物催化反应序列的模块化化学酶促合成(请参见方案)允许顺序构建1,3-二醇的两个立体异构中心,并导致对映体纯净形式的所有四种可能的立体异构体。有机催化醛醇缩合反应的生物相容性使其可以直接用于随后的酶促还原反应中,而无需进行后处理步骤。
