recombinant monooxygease SorbC. In the present work, we systematically screened the effects of structural changes to the natural substrate sorbicillin by HPLC-based analysis and comparative determination of key kinetic parameters. This not only provides important insights into substrate promiscuity of SorbC but also facilitates the efficient chemo-enzymatic preparation of unnatural dimeric sorbicillinoids
类山梨醇是一种真菌类天然产物,具有多种和强大的生物医学活性,从抗生素和抗病毒特性到细胞毒性。在合成上,这些天然产物可以通过使用重组单加氧酶 SorbC 的化学酶方法有效地组装。在目前的工作中,我们通过基于 HPLC 的分析和关键动力学参数的比较确定,系统地筛选了结构变化对天然底物山梨霉素的影响。这不仅提供了对 SorbC 底物混杂性的重要见解,而且有助于高效化学酶促制备具有修饰骨架或羟基化山梨基侧链的非天然二聚山梨醇。此外,天然土木醇 C、土木醇 D 和山青霉素 A 的总合成,

compared with the corresponding properties of 1, 2, vertinolide (4), 3-methoxy-2-methyl-2-cyclohexenone (14), and 2-[(E,E)-2,4-hexadienoyl)]-cyclohexanone (13). The latter was prepared by acylation of the lithium enolate of cyclohexanone with sorbyl chloride. From the spectra of the hexaketides fromV. intertextum several patterns have been extracted which are characteristic for some common and some distinguishing
