The present invention relates to a process for preparing substituted biphenylanilides of the formula I
which comprises reacting a compound of formula II
in the presence of a base and of a palladium catalyst selected from the group of: a) palladium-triarylpliosphine or -trialkylphosphine complex with palladium in the zero oxidation state, b) salt of palladium in the presence of triarylphospine or trialkylphosphine as a complex ligand or c) metallic palladium, optionally applied to support, in the presence of triarylphosphine or trialkylphosphine, in a solvent, with a diphenylborinic acid according to formula (III)
Newly designednicotinamidederivatives were synthesized and characterized using spectral techniques (IR, 1H-NMR, 13C-NMR, and MS). Moreover, these compounds are investigated computationally. B3LYP/6–31 + G(d,p) level is selected as the calculation level in this study. Experimental and calculated IR spectrum were compared to each other. Electronic properties of synthesized compounds are examined using

heterocycles via an intramolecular photochemical cyclization. Herein we report the first examples of the photochemically-induced generation of thieno[3,2-c]quinolin-4(5H)-ones, 16 examples, and benzo[h]-1,6-naphthyridin-5(6H)-ones, 6 examples. Overall, the continuous flow method provides access to complex heterocycles in two steps from commercially available starting materials in good yields and with
已经开发出一种单步连续流动方法,该方法可以通过分子内光化学环化作用快速进入复杂的杂环。在这里,我们报告的第一个例子是光化学诱导的thieno [3,2 - c ] quinolin-4(5 H)-ones,16个例子,和苯并[ h ] -1,6-naphthyridin-5(6 H)-一个,有6个例子。总体而言,连续流方法可从市售原料中分两步轻松获得复杂的杂环,且收率高,且原子效率高于传统的间歇反应。
