The tetracyclic framework of the tetrapetalone A aglycon has been secured through synthesis. A reductivepyrrole alkylation enables the formation of a key tetrasubstituted carbon stereocenter, and the tetramic acid portion of the molecule can be accessed through silicon or boronic ester conjugate addition to an ene-lactam.
通过合成已固定了四petalone A A糖苷配基的四环框架。还原性吡咯烷基化能够形成关键的四取代碳立体中心,并且该分子的四酸部分可以通过将硅或硼酸酯共轭物添加到烯内酰胺中来获得。
