[reaction: see text] Unexpectedly, imidazolidin-2-ones are easily obtained from beta-keto esters upon treatment with tert-butyl nosyloxycarbamate and calcium oxide under mild conditions. The structure of the product was established by X-ray crystallography.
[反应：见正文] 出乎意料的是，在温和条件下，用叔丁基 nosyloxycarbamate 和氧化钙处理 β-酮酯时，很容易得到咪唑啉-2-酮。产物的结构通过 X 射线晶体学确定。
