Interaction of hydrazine with 4-acylisochroman-1,3-dione furnishes benzopyranopyrazole (V) and N-amino-1(2H)-3-alkyl-isoquinolone (VI) in nearly equal amounts.N-Amino-3-alkylisoquinolone is the sole product of interaction of hydrazine with 3-alkylisocoumarin, 4-carboxy-3-alkylisocoumarin and with 2-carboxybenzylalkyl ketone.A number of benzopyrazoles and N-aminoisoquinolones have been synthesised and their structures established.
