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

Add time:09/02/2019 Source:sciencedirect.com
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.
