A Petasis reaction of 2-pyridinecarbaldehydes with various amines and 4-substituted 1,2-oxaborol-2(5H)-ols was developed. In the presence of HCl, the reaction proceeded smoothly under very mild conditions and the corresponding desired products were obtained in medium to excellent yields. This method allows the access a wide range of highly functionalized allylic alcohols, which might be useful compounds
开发了2-吡啶甲醛与各种胺和4-取代的1,2-氧杂硼-2(5H)-醇的Petasis反应。在HCl的存在下,反应在非常温和的条件下顺利进行,并以中等至优异的产率获得了相应的所需产物。这种方法可以使用各种高度官能化的烯丙醇,这可能在药物和材料化学中是有用的化合物。
