The thermal Claisen rearrangement of O-allyl substituted isotetronic acids 1 was successfully carried out within a glass microreactor operated with temperature at 150 °C and a flow rate of 1 mL/h. The strategy provides an efficient alternative way to β-allyl substituted isotetronic acid derivatives 2 in high yields with much accelerated reaction speed.
O-烯丙基取代的等位异酸1的Claisen热重排成功地在玻璃微反应器中进行,该反应器在150°C的温度和1 mL / h的流速下运行。该策略提供了一种高产率的β-烯丙基取代的异戊二酸衍生物2的有效替代方法,其反应速度大大提高。
