Zg. Aliev et al., SYNTHESIS AND CRYSTAL-STRUCTURE OF ETHYL -3-OXO-2-PHENACYL-2,3-DIHYDROPYRROLE-4-CARBOXYLATE, Russian chemical bulletin, 44(8), 1995, pp. 1492-1495
Reaction of 5-phenyl-2,3-dihydro-2,3-furandione with ethyl 3-benzylami
no-2-butenoate, resulting in ethyl 3-oxo-2-phenacyl-2-,3-dihydropyrrol
e-4-carboxylate and benzylamide of N-benzoylpyruvic acid, was studied.
The structure of the pyrrole derivative was confirmed by X-ray analys
is.
