title: An efficient synthesis of novel fused cycloheptatrienes through Mn(II)-mediated formal intermolecular [2 + 2 + 2 + 1] cycloaddition.
abstract: A new method for manganous acetate tetrahydrate mediated formal intermolecular [2 + 2 + 2 + 1] cycloaddition was developed for the synthesis of fused cycloheptatriene derivatives from N-(acylmethyl)pyridinium iodides and naphthoquinone. This method provides an innovative route for the efficient and convenient construction of fused seven-membered carbocycles from simple starting materials.
