simple and efficient photocatalytic method for the synthesis of dihydropyrimidinones (DHPMs) and their derivatives via porous ultrathin carbon nitride nanosheets (p-CNNs) without solvents was demonstrated. The yields of 3,4-dihydropyrimidin-2(1H)-ones/thiones and their derivatives were up to 97.0%. Furthermore, the yield of 5-ethoxycarbonyl-6-methyl-4-phenyl-3,4-dihydropyrimidin-2(1H)-one in the 10th
通过无溶剂的多孔超薄氮化碳纳米片(p-CNNs)合成了一种简单高效的光催化方法,用于合成二氢嘧啶酮(DHPM)及其衍生物。3,4-二氢嘧啶-2(1 H)-酮/硫酮及其衍生物的产率高达97.0%。此外,5-乙氧基羰基-6-甲基-4-苯基-3,4-二氢嘧啶-2(1 H)-第10个周期中的1个保留了其第1个值的98.9%。考虑到环境和经济利益,这项工作表现出各种优点,包括优异的产量,环境友好性,便宜性以及避免使用溶剂和金属基光催化剂。此外,p-CNN的优异性能和对环境无害的反应体系也通过光催化合成12-苯基-9,9-二甲基-8,9,10,12-四氢苯并[ a ] xanthen-11进行了检验。-一个和5-苯基-1(4-甲氧基苯基)-3 [(4-甲氧基-苯基)-氨基] -1 H-吡咯-2(5 H)-一个。这项工作为在温和的反应条件下使用无金属的光催化剂进行三组分反应铺平了道路。
