waste product in the Heck reaction, was found to act as a key catalyst in the practical one-pot Heck-dehydration reaction. A concise synthesis of indiacen A was accomplished in 92% overall yield using a protecting-group-free and redox-neutral strategy. In this synthesis, a novel one-pot reaction with high regio- and stereo-selectivity was developed and further application in the total synthesis of other
发现三烷基铵盐在Heck反应中被认为是废物,在实际的一锅Heck脱水反应中被用作关键催化剂。使用无保护基团和氧化还原中性的策略,以92%的总收率完成了印度dia烯A的简明合成。在该合成中,开发了具有高区域选择性和立体选择性的新型一锅法反应,并将其进一步应用于其他天然产物的总合成中。这种新建立的方法对于合成其他相关的天然产物将是有益的。
