Synthèse et étude de la réactivité d’un nouveau dérivé 4-oxocoumarinique
Written by sctunisie no commentsWe describe in this work a synthetic methodology of the preparation of the ethyl-2-(2,4-dioxochroman-3-ylidenemethyl)amino-3-dimethylaminopropanoate (4) and its further use as a key intermediate to prepare some N-subsituted 3-(aminomethylene)-4-oxocoumarines. All prepared compounds have been fully characterized by mass spectrometry, 1H, 13C and 2D NMR techniques (HMQC HMBC and NOESY).
