Palladium-catalyzed Mizoroki–Heck reactions were carried out in the presence of calcium carbonate in alcoholic solvents. Under these conditions an efficient preparation of functionalized benzalacetones was developed. The reactions were carried out at room temperature and aerobic conditions, giving the products within several minutes in up to 95% isolated yields. Furthermore, some kinetic investigations

A novel photocatalyzed cross-dehydrogenative coupling reaction of N-Boc-tetrahydroisoquinolines with α,β-unsaturatedketones has been developed. This research provides an easy access to a variety of C1-substituted tetrahydroisoquinolines, which can be further transformed into benzo[a]-quinolizine-2-ones, the skeletons of natural products with a wide range of biological activities. The load of the photocatalyst
开发了一种新型光催化N -Boc-四氢异喹啉与 α,β-不饱和酮的交叉脱氢偶联反应。这项研究提供了一种容易获得各种 C1 取代的四氢异喹啉的方法,这些四氢异喹啉可以进一步转化为具有广泛生物活性的天然产物骨架苯并[ a ]-quinolizine-2-ones。光催化剂的负载量低,氧化剂便宜且毒性较小。
