“…Hence the development of rapid, simple, efficient, clean, high yielding, environmentally benign protocol using new catalyst for the synthesis of this compound is desirable. Boric acid is a water soluble inexpensive, stable, readily available, easy to handle catalyst and has been found effective in various transformations such as synthesis of aza Michael 17 , thia Michael 18 , transesterification of ethylacetoacetate 19 ,synthesis of α-hydroxyamides 20 , bromination, oxidation of sulphides 21 , beginelli reaction 21 , 1,5-benzodiazepine derivatives 22 , 2-amino,3-5 dicarbonitrile-6-thio-pyridene 23 . It is therefore important to examine the behavior of boric acid as a catalyst in the synthesis of 1,2,4-triazolo quinolinone derivatives.…”
