An efficient preparation of fused [2,1-b]quinazolinones has been developed utilizing polymer-supported reagents. (±)- Vasicinone was converted into its dione by oxidation with poly (4-vinylpyridiniumdichromate). An efficient method has been developed for the synthesis of (d)- and (l)-vasicinone via asymmetric reduction of pyrrolo[2,1-b]quinazoline-3,9-dione by employing NaBH4/Me3SiCl as the reducing agent and polymer-supported chiral sulfonamide as catalyst.

Sodium iodide in acidic media has been employed for the synthesis of N-arylformamides and N-arylacetamides. The NaI/acetic acid reagent system has also been extended for the synthesis of 1,4-benzodiazepine-2,5-diones, pyrrolo[2,1-c][1,4]benzodiazepine-5,11-diones, and fused [2,1-b]quinazolinones.
