Facile, one-pot synthesis of new phenanthridine derivatives through 1,4-dipolar cycloaddition of phenantridine, activated acetylenes, and aromatic aldehydes
A one-pot, regioselective 1,3-dipolar cycloaddition of in situ generated (diethoxyphosphoryl)difluoromethyl nitrile oxide toward selected alkenes and alkynes is reported. This protocol enables facile access to 3,5-disubstituted isoxazolines and isoxazoles bearing...
AbstractReadily prepared copper nanoparticles are an effective catalyst for 1,3-dipolar cycloaddition of carbohydrate azide and a variety of alkynes that furnishes the corresponding 1,2,3-triazole-sucrose derivatives in excellent yields. Products were screened for their antimycobacterial activity against
