Synthesis and structure of nitroethylpyrrolidone carboxylates
摘要:
3-Methoxycarbonyl-4-phenyl- and 4-(3-pyridyl)-2-pyrrolidones react with 2-aryl(heteryl)-1-nitroethenes to form C(3)-adducts as one or two diastereomers. Their structure was characterized by the IR, (1)H, and (13)C NMR spectroscopy, using the two-dimensional correlation spectroscopy.
