  AgOTf and TfOH co-catalyzed isoquinoline synthesis via redox reactions of O-alkyl oximes

  摘要：

  Under AgOTf and Bronsted acid co-catalysis, O-alkyl o-alkynylbenzaldoxime derivatives undergo a cyclization-induced N-O cleavage to produce isoquinolines with the simultaneous oxidation of O-alkyl group. This redox-based method provides a general access to diverse isoquinoline-derived heterocycles that are simple, efficient, and tolerant of various functional groups from readily available and hydrolytically stable oxime precursors.

  An ammonium acetate assisted gold-catalyzed cascade cyclization reaction of 2-alkynylarylketones is described. Under the reported conditions, a gold-catalyzed intramolecular cyclization of 2-alkynylarylketones takes place through two competing reaction mechanisms—a 5-exo-dig or a 6-endo-dig cyclization—leading to two regioisomeric intermediates: isobenzofuranium or isobenzopyrylium. In the presence

  描述了乙酸铵辅助的金催化的2-炔基芳基酮的级联环化反应。在报道的条件下，金的2-炔基芳基酮的分子内环化反应通过两种竞争的反应机理（5- exo - dig或6 - endo - dig环化）发生，从而产生两种区域异构中间体：异苯并fur或异苯并benzo。在乙酸铵存在下，两种中间体化合物分别进一步重排成2，3-二取代的茚满和1，3-二取代的异喹啉。虽然这两种反应途径经由环化，重排级联进行，金介导的5-外型-挖 该方法是特别值得注意的，因为它提供了2-炔​​基芳基酮的新颖环化方案。

  A copper(I)-catalyzed tandem reaction of 2-bromoaryl ketones, terminal alkynes, and CH3CN is developed, which combines N atom transfer and three-component [3 + 2 + 1] cyclization, and efficiently produces densely functionalized isoquinolines in a facile, highly selective, and general manner. In the reaction, the formation of aromatic C–N bonds along with the complete C–N triple bond cleavage is first
