Abstract :

CReaction of (Z)-2-arylidene-5-oxopyrazolidin-2-ium-1-ides 1 with 3-nitro-2-phenyl-2H-chromenes 2 and conjugated (E)-nitropropenes 3 proceed effectively as [3+2] cycloaddition to give products 4 and 5 as single regio- and diastereomers with good yields.The products obtained are of interest due to their potential biological activity. Study of cytotoxity of the described tetrahydropyrazolo[1,2-a]pyrazolone derivatives is in process.
