Stereocontrolledpalladium(II)-catalyzed intramolecular 1,4-oxidations of dienyl acids and alcohols proceed under mild conditions to give fused δ-lactones and pyrans, respectively, in good yields. The stereo- and regioselectivity was affected by the presence of LiCl and solvent composition (HOAc/acetone). The products obtained were used for further functionalizations using copper(I)-mediated reactions

The invention discloses processes for the preparation of rivaroxaban and its pharmaceutically acceptable salts, solvates, and hydrates thereof. The invention also relates to novel intermediates for the preparation of rivaroxaban.
New types of palladium(II)-catalyzed intramolecular 1,4-dialkoxylation of 1,3-cyclohexadienes are described. The reactions proceed with high regio- and stereoselectivity and provide an efficientroute to novel stereodefined heterocycles such as oxaspirocyclic compounds and fused pyrans.
