work summarizes an investigation of tandem radical cyclizations triggered by O-stannyl ketyls. This organometallic reactive intermediate is prepared from the reaction of tributyltin hydride (nBu3SnH) with a carbonyl functional group by a free radical chain mechanism. Several precursor substrates leading to “separated,” “spiro,” and “fused” cyclopentaniod ring systems were investigated which collectively
这项工作总结了由O-stannyl ketyls触发串联自由基环化的研究。该有机金属反应性中间体是由氢化三丁基锡(nBu 3 SnH)与羰基官能团通过自由基链机理反应制得的。研究了几种导致“分离”,“螺”和“稠合”的环戊二烯环系统的前体底物,这些底物共同具有良好的合成潜力,可用于构建多种取代的多环产物。
