title: Platinum dichloride-catalyzed cycloisomerization of ene-ynamides.
abstract: [reaction: see text] Various ene-tosylynamides react with platinum(II) chloride and lead to bicyclic nitrogenated heterocycles. This unprecedented and easily operated process can be coupled with a hydrolysis of the intermediate cyclic tosylenamides in a one-pot transformation, which provides cyclobutanones.
