Spirocyclic oxindoles are privileged building blocks frequently occurring in many natural products and biologically active molecules.Its’ derivatives could be also used as versatile synthetic intermediates,with simple and flexible synthetic routes that allow the production of large chemical libraries of potential bioactive molecules.However,little efforts so far have been focused on the strategy for spiro-fused carbocyclic frameworks.Recently,our group focused on the study of the application of phosphine catalyzed domino reaction in the synthesis of cyclic compounds.[1] Via a series of studies,we have realized a substrate controlled processes,in which varieties of monocyclic cyclopentenes[2] and bicyclic cyclopentene skeletons[3] were obtained with high yields and stereoselectivities.As the further investigation,we devised and developed a novel domino reaction for the preparation of carbocyclic spirooxindole skeletons with conjugated dienes and methyleneindolinones.
