摘要

提出了一种新的铁催化联芳酮与易得苯甲醇的串联环化和6-外三角脱芳反应。在铁（acac）3和过氧化叔丁基存在下，以苯甲醇为酰化试剂，通过级联氧化/酰化/脱芳化工艺制备了多种酰化螺[5.5]三烯酮。

Iron-catalyzed one-pot tandem oxidation/acylation/dearomatization of biaryl ynones with benzyl alcohols: access to diversified acylated spiro[5.5]trienones

A new iron-catalyzed tandem cyclization and 6-exo-trig dearomatization reaction of biaryl ynones with readily available benzyl alcohols was developed. In the presence of Fe(acac)₃ and tert-butyl hydroperoxide,a variety of acylated spiro[5.5]trienones were prepared through cascade oxidation/acylation/dearomatization process using benzyl alcohols as acylation reagent.
