Stereoselective synthesis of twenty (three 12-, five 13- and twelve 14-membered) macrolides and seventeen functionalized 2,6-trans-disubstituted dihydropyran derivatives have been achieved. The key reactions include an Achmatowicz rearrangement, Ferrier-type alkynylation, Yamaguchi macrolactonization and Lindlar’s hydrogenation. Biological screening of the synthesised compounds showed moderate activity
已经实现了二十(三十二,五十三和十二十四个十四元)大环内酯和十七个官能化的2,6-反式-二取代的二氢吡喃衍生物的立体选择性合成。关键反应包括Achmatowicz重排,Ferrier型炔基化,Yamaguchi大内酯化和Lindlar加氢。合成化合物的生物学筛选显示出对人癌细胞系的中等活性。
