Sažetak
Synthesized 3-acyl-4, 7-dihydroxycoumarins with hydroxylamine-hydrochloride gave oximes which cyclized to 7-hydroxy-3-alkylbenzpyrano(3, 4-d)- isoxazol-4-one on a higher temperature. Bromation of 3-acyl-4, 7-dihydroxycoumarin was carried out in glacial acetic acid in the presence of potassium persulphate as a catalyst. The obtained 3-alfa-bromoacyl-4, 7-dihydroxycoumarins gave 3- (2-amino-5-alkylthiazol-4-yl)-4, 7- dihydroxycoumarins with thiourea.
