Nowadays, cascade reactions (or domino reactions) 1 represent a formidable challenge for modern synthetic chemistry. 2 Those reactions are generally described as multicomponent one-pot processes involving two or more transformations. That strategy offers many advantages over classical "stop-and-go" sequences, for example, in avoiding protecting groups or isolation of reaction intermediates. Besides operational efficiency (step and pot economy), 3 organocascade reactions showed significant advantages for constructing complex molecular frameworks with high selectivity levels (stereo-, chemo-). Not surprisingly, organocascade reactions were successfully used for the stereoselective preparation of valuable spirocycliclic compounds, 4 for example, the privileged scaffold -spirocyclic oxindole derivatives (spirooxindoles). 5 Spirooxindole structural motif appears as a part of various natural or synthetic compounds with remarkable biological activity, including medicinally relevant compounds (Figure ). Organocascade reactions initiated by the Michael reaction are highly efficient for the construction of spirooxindole-fused derivatives, 7 using either oxindoles with nucleophilic C3 (Michael donors) 8-10 or electrophilic methyleneindolinones (Michael acceptors). 11,12 Interestingly, a combination of both types of starting materials was applied by Wang for the preparation of highly-rigid bispirooxindoles via Michael/spirocyclization reaction promoted by bifunctional organocatalyst (Scheme 1A). 13 Recently, our group described Michael/alkylation organocascade reaction of oxindoles with α,β-unsaturated aldehydes efficiently catalyzed by chiral secondary amine producing valuable spirooxindole-fused cyclopentanes (Scheme 1B). 14 Scheme 1.
