Reaction of isatin with acetophenone derivatives gave 3-hydroxy-3-phenacyl oxindole derivative (6), dehydration of (6) gave 3-phenacylidene-2-indolinone derivative (7). Reaction of (7) with sarcosine and acenaphthenequinone yield novel spirooxindole derivatives which are characterized by various spectral methods. The compounds were subjected to antibacterial and antifungal studies and the results are very promising.
