A. Gola et al., Synthesis, NMR spectroscopic and X-ray crystallographic studies of functionalized 2-aminopyrrolin-4-ones, J HETERO CH, 37(4), 2000, pp. 681-686
An efficient method for the preparation of novel cyano derivatives of 4-ami
no-3-hydroxybutenoic acids 4-8 and N-substituted-2-aminopyrrolin-4-ones 9-1
8 is described; the structure of compound 13 has been elucidated with X-ray
analysis.
