Synthesis of New Tetrahydropyrazine and Other Heterocyclic Compounds by Reaction of Hydrazonoyl

Chlorides.

-New cyclization reactions with hydrazonoyl chlorides (II), (V), (X) are described. Only dimerization of (X) occurs in the presence of N,N'-diphenyl thiourea. The formed arylhydrazone products (III), (VI), (VIII) are more potent 5-lipoxygenase inhibitors than thiazole (XI). -(FROHBERG,

Cyclization reactions of a-ketoarylhydrazonoyl chlorides with various dinucleophiles lead to new 1,4-benzothiazine, quinoxaline, tetrahydropyrazine, thiazole, and thiadiazoline derivatives of methyl butanoate or methyl 5-oxopentanoate. The inhibition of 5-lipoxygenase (LO) was determined by monitori
