AbstractA simple, efficient and solvent free approach for the Knoevenagel condensation has been developed which involves grinding of active methylene compounds with aromatic aldehydes over basic alumina. Using this solvent free Knoevenagel approach, a facile and efficient synthesis of 3-cyano and 3-carbethoxycoumarins has also been developed, which involves the grinding of 2-hydroxybenzaldehydes with malononitrile or ethylcyanoacetate respectively over basic alumina followed by grinding with p-toluenesulphonic acid (PTSA) in the same mortar.

A facile synthesis of [5,5]-annulated N-fused heterocycles – pyrrolo[2,1-b]thiazoles and pyrrolo[1,2-b]indazoles via Cu(II)-mediated oxidative [3+2]-annulation between nitroalkenes and azolium ylides was developed. The reaction proceeds in mild conditions with copper (II) trifluoroacetate/2,6-lutidine system as a promoter. The method is applicable to a broad range of nitroalkenes and azolium salts, providing target N-fused heterocycles in moderate to good yields. In the case of α-fluoronitroalkenes unique fluorinated derivatives were accessed via this methodology.
