Intramolecular aminolysis of 2-aminochalcone epoxides using InBr 3 or BiCl3 as efficient catalysts

In the synthesis of aza-flavanone derivatives, several metal halides were screened for their catalytic activity. Among them, BiCl3 and InBr3 catalyze the ring opening of 2-aminochalcone epoxides followed by intramolecular aminolysis

Chalcone derivatives as precursors of 1,2,3,4-tetrahydro-4-quinolones

2-Aryl-1,2,3,4-tetrahydro-4-quinolones were synthesised from 2′-amino-4-methoxychalcone and its 2′-benzenesulphonamido derivative by acid and base catalysis, respectively. The α,β-dibromo and α-bromo-β-methoxy derivatives of 2′-benzenesulphonamido-4-methoxydihydrochalcone cyclised to 2-aryl-3-bromo-1,2,3,4-tefrahydro-4-quinolones as did the corresponding α-bromochalcones. 2′-Amino-4-methoxychalcone formed a stable epoxide.
