Abstract
Abstract The reaction of 6-chloropurine (1) with fourfold excess of hydroxylamine-O-sulfonic acid (HOSA) provided (Z)-1H-purin-6-ylideneaminooxysulfonic acid (2) which can be regarded as a secondary metabolite of ultimate mutagen 6-hydroxylaminopurine (6-HAP). A similar reaction of 1 with twofold excess of HOSA gave a mixture of the substrate and the betaine product which co-crystallized from DMF-methanol-water in the form of complex 3 that proved to be a 1:1 complex 1·2 with offset face-to-face π-stacking interactions between purine rings.
