Arylation of allylphosphonates and application to the preparation of phosphonomethyl-coumarin, -quinolinone and -benzoxepinone skeletons

[Display omitted] An efficient and selective synthesis of Z-(het)arylallylphosphonates is described. The versatile Pd-assisted process also allowed polyarylation sequences leading to star-shaped and binaphthyl derivatives. The methodology could be extended to the preparation of new phosphonomethyl-c...

Description
Summary:[Display omitted] An efficient and selective synthesis of Z-(het)arylallylphosphonates is described. The versatile Pd-assisted process also allowed polyarylation sequences leading to star-shaped and binaphthyl derivatives. The methodology could be extended to the preparation of new phosphonomethyl-coumarin, -quinolinone, and -benzoxepinone architectures in high yields.
