摘要:The present invention relates to novel substituted aryl sulfone intermediates and processes for preparing the same. An aspect of this invention relates to a process for making substituted aryl sulfone intermediates utilizing a one-pot deacylation-carbon/sulfur bond formation step. The invention also relates to a process for preparing intermediates that are used to make the compounds of formula I. Some of the advantages of the present invention include manufacturing flexibility and efficiency, high yield synthesis using a one pot deacylation and carbon-sulfur bond formation step of a thioester intermediate and the like. This and other aspects of the invention will be realized upon review of the specification as a whole.
