资源简介：
Samarium diiodide mediated reductive ring contraction of a substituted tricyclo[2.2.2]oxazine at 25 °C leads to a mixture of cyclopentane and cyclobutane rearrangement products with complete diastereoselectivity in each case. At −78 °C, the anticipated amidocyclohexanol reduction product is obtained exclusively, while the cyclopentane is the sole product at reflux in THF.
