Investigation of the cycloaddition reaction under thermodynamic control of pyrido[2,1-a]isoindole with maleimide derivatives revealed a new rearrangement leading to 2-{2Ј-[(1R)-2,5-dioxopyrrolidinylidene]-2Ј-[(1R)-2,5-dioxopyrrolidinyl)methyl]}phenylpyridine. Their structure was confirmed by Xray di
