Synthesis of some isatin based novel spiroheterocycles and their biological activity studies

摘要

Some new l-{3'-(substituted phcnyl)-spiro[3H-indole-3,2'-thiazolidine]-2,4'(lH)-dione-l'-ylacetainido}-2-phenyl-4-arylid-ine-5-oxoimidazolines have been prepared by reacting 3'-(substituted phenyl)-spiro[3H-indole-3,2'-thiazoIidine]-2,4'(lH)-dione-1-ylacetylhydrazinc with various azalactones which have been evaluated for their antibacterial activity.
