Synthesis of Some New Thieno[2,3-b]pyridines, Pyrimidino[4 ',5 ':4,5]thieno[2,3-b]pyridine and Pyridines Incorporating 5-Bromobenzofuran-2-yl Moiety

摘要

2-Sulfanyl-6-(2-thienyl) pyridine-3-carbonitrile, 1-Amino-6-(5-bromo-benzofuran-2-yl)-2-oxo-1,2-dihydro-pyridine-3-carbonitrile, thieno[2,3-b]pyridins, pyrimidino[4',5': 4,5]thieno[2,3-b]pyridine, quinazoline and carbamate derivatives were synthesized from sodium 3-(5-bromobenzofuran-2-yl)-3-oxoprop-1-en-1-olate with. The newly synthesized compounds were elucidated by elemental analysis, spectral data, and alternative synthesis whenever possible and chemical transportation.
