Ethyl esters of α-(3-chloro-1,4-naphthoquinon-3-yl)crotonic or cinnamic acids were obtained by the reaction of 2,3-dichloro-1,4-naphthoquinone with ethyl esters of N-substituted β-aminocrotonic or β-aminocinnamic acids.These esters were converted by alkal

, p. 1067 - 1069 (2007/10/02)
A new method is proposed for the synthesis of derivatives of indeno-pyrrole-4-ones by intramolecular cyclization of the corresponding 5-(o-carboxyphenyl)pyrroles by trifluoroacetic anhydride.
