on (B2(pin)2), and methyl iodide is reported. Alkenes including styrenes, β-substituted styrenes, and challenging aliphatic olefins were smoothly transferred to the desired methylboration products with excellent diastereoselectivities (dr up to >99:1) and enantioselectivities (er up to 99:1). The utility of this process was demonstrated by the synthesis of naproxen and formal synthesis of two natural
据报道,烯烃,双(频哪醇)二硼(B 2(pin)2)和甲基碘的对映选择性铜催化的硼酸酯交叉偶联反应。将包括苯乙烯,β-取代苯乙烯和挑战性脂肪族烯烃在内的烯烃平稳地转移到所需的甲基硼酸酯产品中,该产品具有出色的非对映选择性(dr高达> 99:1)和对映选择性(er高达99:1)。萘普生的合成和两种天然产物的正式合成证明了该方法的实用性。
