AbstractThe syntheses of methyl 4‐(4‐nitrophenyl)‐3‐oxomorpholine‐2‐carboxylate (3a) and ethyl 4‐(4‐nitrophenyl)‐2‐oxomorpholine‐3‐carboxylate (5b), important building blocks for the synthesis of factor Xa inhibitor rivaroxaban analogs with potential dual antithrombotic activity, via Rh2(OAc)4‐catalyzed OH and NH carbene insertion reactions are described.
