Visible-Light-Driven Aryl Migration and Cyclization of α-Azido Amides
This paper reports two new visible-light-promoted radical reactions of α-azido amides. By catalysis of [Ir(ppy)2(dtbbpy)]PF6 with i-Pr2NEt as the reducing agent, N-aryl α-azido tertiary amides were first converted to the corresponding aminyl radicals through reduction of the azido group; the aminyl radicals then underwent N-to-N aryl migration to give α-anilinyl-functionalized amides. α-Azido secondary amides, on the other hand, reacted with the solvent ethanol and i-Pr2NEt to afford the imidazolinone products.
Ru(II)-Pheox catalyzed N-H insertion reaction of diazoacetamides: Synthesis of N-substituted α-aminoamides
An efficient protocol for the preparation of α-aminoamides was developed via the Ru(II)-dm-Pheox catalyzed N-H insertion reaction of various diazoacetamides with several amines, including aniline. This catalytic N-H insertion reaction was also applied to the synthesis of 2-(2-methylquinolin-4- ylamino)-N-phenylacetamide, a potential antileishmanial agent.
Synthesis of α-amino acid amides: Ruthenium-catalyzed amination of α-hydroxy amides
Give me an N: The catalytic amination of α-hydroxy amides with a variety of amines, including anilines, primary and secondary aliphatic amines, and ammonia, yields a wide range of α-amino amides (see scheme). This atom-efficient amination protocol proceeds efficiently in the presence of a commercially available [Ru3(CO)12]/DCPE catalyst system. Copyright
Synthesis of a novel quinoline derivative, 2-(2-methylquinolin-4-ylamino)-N-phenylacetamide - A potential antileishmanial agent
Some novel quinoline derivatives were prepared and tested for antileishmanial activity. 2-(2-Methylquinolin-4-ylamino)-N-phenylacetamide (2) was found to be significantly more active than the standard antileishmanial drug sodium antimony gluconate (SAG) i
