Novel base catalysed rearrangement of sultone oximes to 1,2-benzisoxazole-3-methane sulfonate derivatives.

Arava VR, Siripalli UB, Nadkarni V, Chinnapillai R - Beilstein J Org Chem (2007)

Bottom Line: A new process for the preparation of 1,2-benzisoxazole-3-methanesulfonates and 4-oximino-2,3-dihydrobenzoxathiin-2,2-dioxides (sultone oximes) is described.These compounds are important intermediates for the preparation of zonisamide, an anti-convulsant drug.
