GRAPHICAL ABSTRACT ABSTRACT A one-pot methodology for the synthesis of α,α-disubstituted aryl-1-ethanones via the Wittig-Horner reaction has been developed and described in this manuscript. Both aryl/alkyl and dialkyl α-branched arylethanone were obtained in high yields (up to 96%) without the use of any metal catalysts. A total of 14 α,α-disubstituted arylethanone derivatives were synthesized based
图形摘要摘要 本手稿开发并描述了通过 Wittig-Horner 反应合成 α,α-二取代芳基-1-乙酮的一锅法。在不使用任何金属催化剂的情况下,以高产率(高达 96%)获得了芳基/烷基和二烷基 α-支化芳基乙酮。基于这种将羰基碳 (sp2) 轻松转化为 sp3 碳的简单方法,共合成了 14 种 α,α-二取代芳基乙酮衍生物。这种通用方法有望进一步促进使用取代酮作为合成构建单元来构建各种α-支化芳基酮。
