Straightforward N-alkylation of diketopyrrolopyrroles through Mitsunobu reaction with benzyl, α-branched, and chiral alcohols
The N-alkylation of diketopyrrolopyrroles (DPPs) represents a fundamental step to ensure solubility and further processability. Commonly used nucleophilic subtitution on halogenated derivatives is replaced in this work by Mitsunobu reaction...
