Several 4-amino-5-haloisothiazoles have been prepared and used to synthesize isothiazolo[4,5, 5 ]pyrazines (see Section 4.05.7.4). Thermal decomposition of 5-azidoisothiazoles yields isothiazoles condensed with a second heterocyclic ring. [Pg.584]

The isothiazolo[4,5-6 4, 5 -e]pyrazine system 51 has been obtained by cyclizing the isothiazole 50 <97MC97> and the reaction of 2,3-dichloro-5,8-dimethoxyquinoxaline with thiourea yields the pentacyclic system 52 <96JCS(P1)2443>. [Pg.283]

The known a-biomoesier 102 has been used to malm the imidazo(l,2-a]pyrazine analogue 103 of adenosine as outlined in Scheme 10, and the isothiazolo(4,5-d)pyritiiidine 104 and its a-... [Pg.258]
