Diastereoselective synthesis of novel 2,5-dioxopyrrolidine derivatives via biocatalytic domino reactions

Abstract

A series of novel 2,5-dioxopyrrolidines were synthesized by the one-pot reaction of coumarin-3-carboxylic acids 1 with thiourea derivatives and alkyl isocyanides in the presence of Fe$_{3}$O$_{4}$ NPs @ lipase as heterogeneous reusable nanobiocatalysts with high yields.
