Abstract: | The reactions of 4-bromo-1-(5 -nitro-2 -furyl)but-1-en-3-one and its 2-methyl and 2-chloro derivatives with thiourea and its N-allyl and N-phenyl derivatives have yielded 2-amino-4- -5 -nitro-2 -furyl)-vinyl]thiazole and its - and N-substituted derivatives. 2-Amino-4- -(5 -nitro-2 -furyl)vinyl]thiazole and its -methyl derivative have also been prepared by the direct reaction of the corresponding , -unsaturated ketones with bromine and an excess of thiourea in chloroform, as was shown by a comparison of UV spectra. A series of N-acyl derivatives of the aminothiazoles has been obtained. UV and IR spectra are given. |
