1.5.2.3.3 Induction by a Nucleophilic Step

DOI: 10.1055/sos-SD-219-00174

Wang, S.-H.; Tu, Y.-Q.; Tang, M.Science of Synthesis: Applications of Domino Transformations in Organic Synthesis, (20151344.

Other than the two major reaction types outlined in Sections 1.5.2.3.1 and 1.5.2.3.2, a domino process involving a ring closure can also be initiated by a nucleophilic step, which is normally induced by a Lewis basic reagent.
