A series of dispiro[indoline-3,2'-pyrrolidine-3',3″-indolines] was synthesized via a multicomponent polar [3 + 2] cycloaddition (32CA) reaction of isatin derivatives, sarcosine and (<i>E</i>)-3-(2-oxo-2-(pyren-1-yl)ethylidene)indolin-2-one derivatives. The regio- and stereochemistries of the cycloadducts were established on the basis of one-dimensional (1D) (<sup>1</sup>H-, <sup>13</sup>C-, <sup>13</sup>C-CRAPT NMR) and two-dimensional (2D) homonuclear and heteronuclear correlation NMR spectrome ...[more]
