Synthesis of thieno[2′,3′(3′,4′ or 3′,2′):5,6]azepino[2,1-a]isoindolediones from N-Thienyl-2(3)-ylmethylphthalimides
Résumé
Reduction of N-thienylmethylphthalimides 5a-e followed by the Wittig reaction gave the substituted acetic acids 8a-e. Their corresponding acyl chlorides where cyclized in the presence of aluminium trichloride to furnish the cyclic ketones 9a-e. Treatment of these ketones with bromine followed by triethylamine, or with selenium dioxide led to the thienoazepinoisoindolediones 1a-e.
