ONE-POT SYNTHESIS OF PHTHALAZIN-4-HETEROYL-4HPYRAN DERIVATIVES IN [BMIM][OH

Author: D. P. Loka Maheshwari, B. Satyanarayana
Abstract

A [bmim][OH] mediated, green and efficient synthesis of phthalazines derivatives have been developed by condensing phthalic acid (1),
ethyl cyanohydrazide (2), heteroaromatic aldehydes (3a-3f) and active methylene compounds (4) at 60-65 oC for 60-90 min. The
importance of this method includes shorter reaction time and high yield.
