Synthesis of 5H-Pyrazino(2,3-b)indoles from Indole-2,3-dione Derivatives. -The reaction of the N-acetylisatins (I) with ethylenediamine yields the products (III). After dehydrogenation these compounds and their analogues (IV) after deacetylation are cyclized by heating to the title products (VI). N

The present article reports our approach toward the synthesis of spiro compounds via indol-2,3-diones. Thus, reaction of indol-2,3-dione derivatives with a secondary cyclic amino acid, namely, (R)-(β«-)Χβ¬thiazolidine-4-carboxylic acid, affords a thiazolo-oxazolidinone as the main product. When the re
