An asymmetric triple cascadeorganocatalyticreaction was carried out in water, which led to the construction of polyfunctional cyclohexene building blocks with multiple stereocenters with good diastereoselectivity and excellent enantioselectivity. This asymmetric triple cascade process was found to be quite effective for various nitroalkenes, including those with aliphatic substituents.

multi-component domino reaction is used as a key process for the stereoselectivesynthesis of polysubstituted mono- and bicyclic cyclohexene-carbaldehydes. Furthermore, the extension of the domino reaction and further synthetic transformations of the cascade products were investigated. The combination of the three-step cascade with an intramolecular Diels–Alder reaction opens up an entry to tricyclic decahydroacenaphthylene

The design of biologically inspired, multi-component cascadereactions enables the targeted synthesis of assorted structurally complex products. Similar to regulation in cells the reaction path is controlled by the substrate concentration and complex enantiopure products with high structural diversity are provided.
