Abstract

The IR-spectra of compounds IVd, e, and Va have two absorption bands of nonequivalent amide carbonyls in the 1610-1630 cm -I and 1700-1710 cm -I regions [3] and stretching vibration bands of the hydroxyl and two NH groups in the 3400-3420 cm -I region. EXPERIMENTAL (CHEMICAL) The purity of the synthesized compounds was confirmed by TLC on Silufol UV-254 plates in a 10:9:1 benzene-ether-acetone system, iodine developer. IR-spectra ...
