The reaction of 2-amino-and 2-acylaminothiazoles with O-mesitylenesulfonylhydroxylamine resulted in the ready formation in the corresponding 3-aminium salts, which were converted into thiazolo[3,2-b]-s-triazoles in high yields.
的反应的2-氨基和2- acylaminothiazoles与ö -mesitylenesulfonylhydroxylamine导致准备形成在相应的3-铵盐,将其转化成噻唑并[3,2- b ] -小号高收率-triazoles。
