Multicomponent domino reaction from beta-ketoamides: highly efficient access to original polyfunctionalized 2,6-diazabicyclo[2.2.2]octane cores.
We describe a new multicomponent domino reaction from beta-ketoamides, involved as substrates and as nucleophilic partners. We obtain highly functionalized and original 2,6-diazabicyclo[2.2.2]octane cores (2,6-DABCO) in a five-step one-pot sequence, which is fast, environmentally friendly, operationally simple to manage, and combines step- and atom-economic aspects.
