Abstract
AbstractProduction of renewable, high‐value N‐containing chemicals from lignocellulose will expand product diversity and increase the economic competitiveness of the biorefinery. Herein, we report a single‐step conversion of furfural to pyrrole in 75 % yield as a key N‐containing building block, achieved via tandem decarbonylation–amination reactions over tailor‐designed Pd@S‐1 and H‐beta zeolite catalytic system. Pyrrole was further transformed into dl‐proline in two steps following carboxylation with CO2 and hydrogenation over Rh/C catalyst. After treating with Escherichia coli, valuable d‐proline was obtained in theoretically maximum yield (50 %) bearing 99 % ee. The report here establishes a route bridging commercial commodity feedstock from biomass with high‐value organonitrogen chemicals through pyrrole as a hub molecule.
