The cycloaddition–retroelectrocyclization reaction is a useful reaction for the conversion of electron-rich alkynes and electron-poor alkenes into buta-1,3-dienes.1 We have recently shown that this reaction is more widely applicable to ester-substituted alkenes to afford compounds of type 1.2 In this presentation we will describe how compounds of type 1 can be efficiently and rapidly converted into highly substituted pyrroles 2. Further one-step functionalization allows isolation of substituted pyrroles of type 3 and, 4 and 2H-pyrrol-2-ones 5, the latter of which exhibit strong chromophoric behaviour and a bathochromic shift upon protonation
