1,3-Dipolar cycloadditions of substituted vinylphosphonate with nitrile oxides or nitrones

1,3-dipolar cycloaddition reactions are among the most important synthetic manipulations allowing the construction of five-membered ring carbocycles and heterocycles. Vinylphosphonates and its analogues have found wide application in organic chemistry during the last two decades and have become very useful for the construction of functionalised organophosphorous compounds. In this report, we have developed a method for the synthesis of beta-Substituted vinylphosphonates and the novel structural heterocyclic compound containing a phosphonyl group.
