Abstract: A faciles ynthetic methodology of novel azolyl, azinyl and azepinyl phosphonates ascyclic α-aminophosphonates was described. Chromonyl α-aminophosphonates,γ-pyranyl and γ-pyridinyl phosphonates were also prepared. The methodologydepends on reaction of 6-methyl-3-formylchromone, nitrogen and carbon nucleophiles in thepresence of diethyl phosphite in one-pot three component under solvent-freeconditions. The products were evaluated for their antimicrobial activities andantioxidant properties.
Keywords: α-Aminophosphonate, Phosphonate, Chromone, Ring opening and Ring closure, Antimicrobial, Antioxidant
