  Cine Substitution of Arenes Using the Aryl Carbamate as a Removable Directing Group

  摘要：

  An efficient and controlled means to achieve a rare cine substitution of arenes is reported. The methodology relies on the strategic use of aryl O-carbamates as readily removable directing groups for arene functionallzation. The removal of aryl carbamates is achieved by employing an airstable Ni(II) precatalyst, along with an inexpensive reducing agent, to give synthetically useful yields across a range of substrates. The net cine substitution process offers a new strategy for analogue synthesis, which complements the well-established logic for achieving arene functionalization by ipso substitution.

  Combined Directed Metalation – Suzuki-Miyaura Cross Coupling Strategies. Synthesis of Isomeric Chromenopyridinones and Related Annulated Analogues

  摘要：

  A general strategy encompassing a Directed ortho Metalation (DoM) - Suzuki-Miyaura cross coupling and Directed remote Metalation (DreM) sequence for the synthesis of 5H-chromeno[4,3-c]pyridin-5-ones 5a-j, 5H-chromeno[3,4-b]pyridin-5-ones 6a-j, 5H-chromeno[3,4-c]pyridin-5-ones 13a-d, 12H-benzo[7,8]chromenopyridin-12-ones 16a-c, 17a-c, and pyrido[31,41:4,5]pyrano[2,3-e]indazol-5(111)-one analogues 18, 28 is reported. Thus, using the powerful directed metalation group properties of aryl O-carbamates 9a-h, 14a-c metalation-boronation followed by Suzuki-Miyaura coupling with 3-bromopyridine affords a variety of azabiaryls 7a-i, 8a-b, 12a-c, 15a-c which, upon DreM reaction leads to several series of chromenopyridinones 5a-j, 6a-j, 13a-d and pyridonaphthopyrones 16a-c, 17a-c. The synthesis of an unusual pyridopyranoindazolone 18 is also described.
