Light-induced synthesis of 3,7-disubstituted bisisothiazolo[4,5-b:4′,5′-e]pyrazines from 3-substituted 4-dibromoamino-5-haloisothiazoles
摘要:
A new procedure was developed for the synthesis of 3,7-disubstituted bisisothiazolo[4,5-b:4',5'-e]pyrazines from 3-substituted 4-dibromoamino-5-haloisothiazoles under UV irradiation. N,N'-Bis(5-haloisothiazol-4-yl)diazenes were obtained as by-products.
