Carboxylic acids and amine/amino acid reactants can be converted to amides and peptides at neutral pH within 5-36 h at 50 °C using catalytic quantities of a redox-active benzoisothiazolone and a copper complex. These catalytic "oxidation-reduction condensation" reactions are carried out open to dry air using O2 as the terminal oxidant and a slight excess of triethyl phosphite as the reductant. Triethyl

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。
