A new total synthesis of the alkaloid variolin B is achieved by a selective and sequential palladium-mediated functionalization of a trihalo-substituted pyrido[3′,2′:4,5]pyrrolo[1,2-c]pyrimidine. This intermediate is obtained by a new heterocyclization reaction between an appropriate bromomethyl azaindole and N-tosylmethyl dichloroformimide. The methodology may be effective for the synthesis of some analogs by substitution on the relatively unexplored C4 and C9 positions of the alkaloid.

The reaction of aliphatic and aromatic isonitriles with sulfuryl chloride provides an efficient, general route to the corresponding dichlorides without byproducts of free-radical substitution.
