Trialkylammonium salt, recognized as a 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 natural products. This newly established method would be beneficial for the synthesis of other relevant natural products.

使用实际的一锅法反应进行印度in虫A的全合成：由一种主要的废品促进，及其在天然产物合成中的效用

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。
