    Method for the Large-Scale Synthesis of Multifunctional 1,4-Dihydro-pyrrolo[3,2‑<i>b</i>]pyrroles by Mariusz Tasior (1457731)

    Published 2020
    “…A thorough investigation has enabled the optimization of the synthesis of 1,4-dihydro-pyrrolo­[3,2-<i>b</i>]­pyrroles. Although salts of such metals as vanadium, niobium, cerium, and manganese were found to facilitate the formation of 1,4-dihydro-pyrrolo­[3,2-<i>b</i>]­pyrroles from amines, aldehydes, and diacetyl, we confirmed that iron salts are the most efficient catalysts. …”
