Abstract
This thesis describes the utility of isatin as a key starting
material for the preparation of a novel series of isatins
derivatives and studies the antimicrobial and fluorescent
activities of these compounds.
Synthesis of spiro[indoline-3,4'-pyridine]-3',5'-dicarbonitrile II
derivatives
Spiro-indoline pyridine II was synthesized to be used as a
starting material for synthesizing some new heterocyclic
compounds containing isatin moiety. It was found that the
reaction of isatylidene malononitrile I with malononitrile and
ethyl thiol in presence of ammonium acetate gave compound
II when the reaction was continued for 10 min at 55 o C
(Scheme A).
