Triethylborane-mediated radical allylation was performed from Morita–Baylis–Hillman alcohols with no need of protecting group. The radical conjugated addition–elimination reaction is highly selective, and trisubstituted E-alkenes were obtained. This reaction opened a new route for the preparation of functionalized α,β-unsaturated ketones.

自由基烯丙基化：来自 Morita-Baylis-Hillman 加合物的 E 选择性自由基共轭加成消除反应

三乙基硼烷介导的自由基烯丙基化是由 Morita-Baylis-Hillman 醇进行的，不需要保护基团。自由基共轭加成消除反应具有高度选择性，得到了三取代的 E-烯烃。该反应为功能化α,β-不饱和酮的制备开辟了一条新途径。
