INVESTIGATIONS ON CHROMONE DERIVATIVES. PART X. REACTIONS OF 2-CHROMONECARBOXYLIC ACID WITH ETHYLENEDIAMINE AND ITS DERIVATIVES
Reactions of 2-chromonecarboxylic acid with ethylene- and N-methylethylenediamine were investigated; the structure of reaction products was established and course of reaction was suggested.The obtained 2,3-dihydro-1,4-diazepine-5(7)-carboxylic acids reacted differently when affected by bi-functional amines.
