Abstract

Abstract Multistep syntheses of two “carbocyclic” analogues 2 and 3 of topiramate (1) were effected with excellent stereocontrol. Two key reactions employed were: deoxygenation- rearrangement of an enone with p-tosylhydrazine and catecholborane (14--> 15 and 5--> 7) and face-selective vicinal dihydroxylation with OsO 4 (viz. 15--> 16 and 8--> 9).
