Summary, etc. <p>1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) as a highly efficient bicyclic amidine catalyst promoted one-pot <br /> multi-component synthesis of biologically active 1<em>H</em>-pyrazolo [1, 2-b] phthalazine-5, 10-dione derivatives <em>via</em> one-pot <br /> four-component condensation reaction of phthalimide, hydrazine monohydrate, aryl aldehydes and malononitrile under solvent-free conditions through simple filter with no necessity of chromatographic purification steps. Use of safe, <br /> non-volatile, non-corrosive, highly efficient, readily available and easy to handle of catalyst, one-pot reaction, high yields and short reaction times, economical and convenient synthesis, solvent-free conditions and operational simplicity are among the other added advantages that make this approach an attractive alternative for the synthesis of these biologically active compounds.</p>
