responsible, mild method for the synthesis of functionalized 1,3-butadienes is presented. It utilizes allenic esters of varying substitution patterns, as well as a wide range of boron-based nucleophiles under palladium catalysis, generating sp–sp2, sp2–sp2, and sp2–sp3 bonds. Functional group tolerance measured via robustness screening, along with room temperature and aqueous reaction conditions highlight
提出了一种对环境负责的温和的方法,用于合成官能化的1,3-丁二烯。它利用了不同取代模式的烯丙酸酯,以及在钯催化下的多种硼基亲核试剂,生成了sp–sp 2,sp 2 –sp 2和sp 2 –sp 3键。通过健壮性筛选以及室温和水性反应条件测量的官能团耐受性突出了该方法的广度和在合成中的潜在用途。
