• Catalytic Enantioselective Direct Aldol Addition of Aryl Ketones to α‐Fluorinated Ketones
  作者：Connor J. Thomson、David M. Barber、Darren J. Dixon

  日期：2020.3.23

  catalytic enantioselective synthesis of α-fluorinated chiral tertiary alcohols from (hetero)aryl methyl ketones is described. The use of a bifunctional iminophosphorane (BIMP) superbase was found to facilitate direct aldol addition by providing the strong Brønsted basicity required for rapid aryl enolate formation. The new synthetic protocol is easy to perform and tolerates a broad range of functionalities

  electron-transfer (PCET)-triggered enamido C(sp2 )-H diphosphorylation. This reaction represents a rare example of realizing the challenging double C-P bond formation at a single carbon atom, thus providing facile access to a broad variety of structurally diverse bisphosphonates from simple enamides under silver-mediated conditions. Initial mechanistic studies demonstrated that the diphosphorylation involves
