| 摘 要： | 选择数种苯硒酯作为产生酰基自由基的母体，并按照作者已建立的方法合成．用三丁基氢化锡处理苯硒酯所产生的相应的酰基自由基按５－ｅｘｏ－ｔｒｉｇ或６－ｅｎｄｏ－ｔｒｉｇ的方式环合产生环戊酮与环己酮衍生物，环合收率高，在苯硒酯母体上的取代基团对此环合反应的位置选择性产生了重要的影响

ACYL RADICAL CYCLISATIONS |

| Abstract: | Several phenylselenyl esters were selected as precursors of acyl radicals and synthesised by our established method. Treatment of these phenylselenyl esters with tributyltinhydride and AIBN generated the corresponding acyl radicals, which were found to proceed in 5 exo trig or 6 endo trig cyclisations to afford high yields of cyclopentanones and cyclohexanones, The substitution groups on the substrates have played an important role on the regioselectivity of cyclisations. |
