four component couplingreaction of dialkyl but-2-ynedioate, twodifferent amines, and an aldehyde. The reaction is site-selective with respect to aromatic and aliphatic amines. Environmentally benign reaction procedure, excellent yields, tolerance of varieties of functionalities in the reactants, a wide variety of products and reusability of the catalyst make the methodology highly beneficial for
The multicomponent domino reaction synthesis of dihydro-2-oxopyrroles has been performed using the sulfonated metal–organic framework, UiO-66-SO3H (UiO is the University of Oslo), as a highly efficient acid catalyst.

We report efficient synthetic methodologies for the preparation of 3-amino and 3-hydroxy 3-pyrrolin-2-ones (unsaturated γ-lactams) through a multicomponent reaction of amines, aldehydes and acetylene or pyruvate derivatives. The densely substituted γ-lactam substrates show in vitro cytotoxicity, inhibiting the growth of the carcinoma human tumor cell lines RKO (human colon epithelial carcinoma), SKOV3
A polyoxometalate immobilized on MOF‐5 (POM/MOF‐5) material has been synthesized and evaluated for the diversity‐oriented synthesis of poly‐functionalized 3‐pyrrolin‐2‐ones via pseudo‐four‐component reaction between dialkyl acetylenedicarboxylate, amines, and aldehyde. The catalyst can be separated from the reaction mixture and reused at least five times with superior activity.
