An efficient protocol for the Morita–Baylis–Hillman (MBH) reaction of dicyclopentadienone using CTAB has been developed. The MBH adduct was subsequently transformed to its acetate and bromide derivatives. The 1,3-bielectrophilic character of the MBH acetate and bromide was further explored with various 1,3-binucleophiles to construct various oxa-, thia- and aza-heterocycles. These reactions proceed
已经开发了一种使用 CTAB 进行双环戊二烯酮的 Morita-Baylis-Hillman (MBH) 反应的有效方案。MBH 加合物随后转化为其乙酸盐和溴化物衍生物。用各种 1,3-双亲核试剂进一步探索了 MBH 乙酸盐和溴化物的 1,3-双亲电特性,以构建各种氧杂环、硫杂环和氮杂杂环。这些反应通过在碱性条件下将 1,3-双亲核试剂级联双迈克尔加成到 MBH 乙酸盐/溴化物中进行。已经证明了这些反应对放大和产物在环戊烯酮稠合色酮和噻吩并吲哚合成中的应用的适应性。
