Abstract
A one-pot synthesis of electron-poor O-vinyl pyrrolidine in fairly high yields by the reaction of N-hydroxysuccinimide and dialkyl acetylenedicarboxylates in water-acetone media is reported. The structures of these compounds were confirmed by IR, 1H and 13C NMR spectroscopy. The NMR spectra indicated that E- and Z-isomers of the products are formed.
