Twelve 4-substituted semicarbazone derivatives of o- and p-chloro- as well as 2,6-dichlorobenzaldehyde were synthesized and investigated for antihypertensive activity in spontaneously hypertensive rats. Several of the compounds synthesized (viz. 1, 6, 7, and 15) exhibited potent antihypertensive effects when orally administered. The same compounds were not hypotensive in the normotensive dog.

Deprotection of phenylhydrazones, semicarbazones and oximes to their corresponding carbonylcompounds have been carried out in good to excellent yields (83-96 %) by using citric acid as organic catalyst in water as a medium of reaction under microwave irradiation.
