The diepoxides 8 and 9 were prepared by Horner-Emmons and aldol coupling reations from 21 and 13, respectively. The derived β-diketones 22 and 24 were cyclised under acidic conditions to generate the C1-C22 segment 7, which contains the ABCD rings of etheromycin.
通过Horner-Emmons和羟醛偶联反应分别从21和13制备二环氧化合物8和9。将衍生的β-二酮22和24在酸性条件下环化以产生C 1 -C 22区段7,其包含醚霉素的ABCD环。
