Novel Base-induced Reactions of Substituted (1,2-Benzisoxazol-3-yl)acetates

The reactions of substituted (1,2-benzisoxazol-3-yl)acetates with strong bases are described.The esters (1) and (2) having electron-donating and dialkylamino substituents undergo novel ring transformations on treatment with NaH, ButOK, or MeONa in DMF to afford the 2H-azirines (8) and the 3-iminobenzofurans (18), respectively, while under similar conditions the halogeno esters (3) dimerize to give the ethylenedicarboxylate (24).Treatment of the esters (4)-(7) having electron-withdrawing substituents with NaH in DMF results in the recovery of the starting esters.However, on treatment of the sulphinyl esters (6) with MeONa in methanol, C-S bond cleavage occurs to afford methyl arylsulphinates (27).
