The ¹H and ¹³C 2D NMR studies of pyrrolinones derivatives were performed using the method of proton detected 2D 1 H, 13 C correlation spectroscopy. HMQC and HMBC experiments were achieved in order to obtain the unambiguous assign-ment of the structures. (Keywords: ¹H and ¹³C 2D NMR, pyrrolinones, HMQC and HMBC)
