The fragmentation reaction of the optically pure 2-aryl-3-alkylcyclopropylcarbinyl radicals 1 proceeded selectively to generate a benzyl radical and produce the optically pure 4-aryl-3-alkyl-1-butenes 2, which can serve as synthetically useful chiral building blocks.
                                    光学纯的2-芳基-3-烷基环丙基羰基基团1的裂解反应选择性地进行以生成苄基并产生光学纯的4-芳基-3-烷基-1-
丁烯2,它们可用作合成上有用的手性结构单元。
