Abstract
On treatment with diazomethane, 2,4,6/3,5‐penta‐acetoxy‐cyclohexanone(penta‐O‐acetyl‐myo‐inosose‐2 or ‐scyllo‐inosose) gave only a spiroepoxide. In contrast, replacement of diazomethane by higher diazoalkanes furnished a mixture of alkylspiroepoxides and of ring expansion products (cycloheptanone derivatives). The configuration and the reactions of the spiro‐epoxides have been studied.
