strategy has been used to concisely and efficiently complete the synthesis of (+)-mintlactone and (–)-isomintlactone via SmI2-induced intramolecular radical cyclization, two rings and a stereocenter were constructed in one step. In the synthesis, the stereochemistry of the final natural product is set relative to the stereocenter of (–)-citronellol and favored coordination transition state of samarium
一种发散策略已被用于通过 SmI2 诱导的分子内自由基环化简洁有效地完成 (+)-薄荷内酯和 (-)-异薄荷内酯的合成,一步构建两个环和一个立体中心。在合成中,最终天然产物的立体化学是相对于 (-)-香茅醇的立体中心和钐原子与底物的有利配位过渡态而设定的。
