  Synthesis of Phosphaisocoumarins via Iodocyclization

  摘要：

  4-lodophosphaisocoumarins can be prepared in good yield and with high regioselectivity under mild conditions by the reaction of o-(1-alkynyl)phenylphosphonates with I-2 or ICI. The present reaction represents the first example of a phosphonate iodocyclization onto a C-C triple bond. The resulting iodides can be further elaborated using palladium-catalyzed coupling reactions.

  A series of 4-halophosphaisocoumarins were prepared with high regioselectivity in good to excellent yields under mild conditions by the reaction of 2-(1-alkynyl)phenylphosphonic acid diesters with I2 in CHCl3 or ICl in CH2Cl2, or by the reaction of 2-(1-alkynyl)phenylphosphonic acid monoesters with NBS or NCS in DMF. Whether the alkynylphosphonates could cyclize or not was affected by the substituents
