A concise synthesis of three members of the withasomnine family of natural products is reported. The synthesis features a regioselective sydnone-alkynylboronate cycloaddition followed by Suzuki cross coupling and silyl group removal, and marks the first divergent approach to this family of pyrazole based natural products.
