肟醚2a-e与Bu(3)SnH环化生成烷氧胺-3-甲基-铬醚3a-e。当肟醚7a， b在类似条件下转化为二苯并[b，e]氧平8a， b时，观察到七元环的形成。1-甲氧基氨基indanes 12a， b由底物11a， b环化得到，顺式环化产物15a， b和18分别由化合物14a， b和17得到。
The oxime ethers 2a-e have been cyclised with Bu(3)SnH to the alkoxyamino-3-methylidene-chromanes 3a-e. Seven-membered ring formation was observed when the oxime ethers 7a, b were converted into the dibenzo [b,e] oxepines 8a, b under similar conditions. 1-Methoxyaminoindanes 12a, b were produced from the cyclisation of the substrates 11a, b and the cis-fused cyclic products 15a, b and 18 were obtained from compounds 14a, b and 17, respectively.
