Synthesis of Saturated Five-Membered Nitrogen Heterocycles via Pd-Catalyzed C N Bond-Forming Reactions
Saturated five-membered nitrogen heterocycles, such as pyrrolidines, indolines, and isoxazolidines, appear as subunits in a broad array of biologically active and medicinally significant molecules [1]. As such, the synthesis of these compounds has been of longstanding interest. Many classical approaches to the construction of these heterocycles involve the use of C N bond-forming reactions such...
متن کاملRecent developments in the synthesis of five- and six-membered heterocycles using molecular iodine.
Heterocyclic scaffolds represent the key structural subunits of many biologically active compounds. Over the last few years iodine-mediated reactions have been extensively studied due to their low cost and eco-friendliness. This Review covers advances in the field of iodine-mediated synthesis of heterocyclic compounds since 2006, especially with an emphasis on mechanisms of ring formation. In t...

In this investigation a simple synthetic method for the synthesis of trifluoromethyl-1H-benzo[e][1,2,4]triazolo[1,2-a][1,2,4]triazine-1,3(2H)-diones and (trifluoromethyl)benzo [5,6][1,2,4]triazino[1,2-b]phthalazine-8,13-diones has been developed using urazole or phthalazine and aceteimidoyl chloride derivatives at room temperature under ultrasound irradiations. In the comparison to the conventi...

15 صفحه اولAromatic Electronic Delocalization of Benzo Derivatives of Five-membered Heterocycles
The aromaticity of some bicyclic heterocycles is discussed with the aid of the configuration analysis of the expansion coefficient matrices and the similarity analysis of the density matrices. The iso-it-electronic [9] annulenyl anion is taken as the aromatic reference compound for all the heterocyclic compounds considered. The restflts are compared with · those previously obtained from conside...
