Benzopyranyl Phosphonate and β-Phosphono Malonates Derivatives: An Exciting Breakthrough in Chemistry

摘要

In this review, we paid attention to the reported methods and recent advances in the development of 2-amino-3-cyano-4H-chromen-4-yl-phosphonates and functionalized β-phosphono-malonates heterocyclic compound. Small-molecular architectures are considered with the highlighting on their structural design and synthesis approach. The scope of the 2-amino-3-cyano-4H-chromen-4-yl-phosphonates and functionalized β-phosphonomalonates heterocyclic compound via reactions like Knoevenagel, Pinner-cyclisation and advanced phospha-Mi-chael addition reactions using different catalyst for synthesis is listed up to 2020.
