چکیده
|
Ethyl (2e)-4-bromo-3-ethoxybut-2-enoate (2) and ethyl (2e)-3-ethoxy-4-(2- and 4-nitrophenoxy)but-2-enoates (4 and 5) have been synthesized and used as synthones for the preparation of some new ethyl (2z)-2h-1,4-benzoxazin-3(4h)-ylideneacetate (6), 1-(substituted phenyl)-4-hydroxy-1,5-dihydro-2h-pyrrol-2-ones (9) and 4-ethoxy-1-(4-bromophenyl)-1,5-dihydro-2h-pyrrole-2-ones (11). the structures of all synthesized compounds were confirmed by elemental analyses, ir, 1h-nmr and 13c-nmr spectroscopy and mass spectrometry.
