In conclusion, we have reported herein that dialkyl
phosphites are powerful reagents for radical translocation/
cyclization reactions that start from readily available terminal
alkynes. A simple one-pot procedure has been developed.
The excess reagent is easily removed by evaporation, and
filtration through a short pad of silica gel affords a clean
reaction product. The cyclic phosphonates produced by this
reaction cascade are particularly attractive for further transformations.[
11, 19, 20] Application of this process to the synthesis
of natural products is currently underway.

最后, 有报道说,我们这里有强大的试剂磷酸烷基自由基易位/环化反应,从现成 末端炔烃. 简单一锅煮程序已经研制成功. 除去过剩试剂易挥发、 经过过滤和短期垫硅胶带给清洁反应产物. 这种反应所产生的环状膦级联进一步转变尤其具有吸引力. [11,19, 20]应用这一过程的自然产品正在合成.
总而言之，我们此中报告了亚磷酸盐是强有力的试剂为根本迁移，这个过程的应用到自然产品综合当前进行中。一个简单的一罐做法被开发了。蒸发容易地去除剩余试剂，并且滤清通过矽土凝胶一个短的垫买得起一个干净的反应产品。 循环phosphonates由这反应 小瀑布生产了为进一步变革是特别有吸引力的[ 11, 19, 20] 这个过程的应用到自然产品 综合当前进行中。
