through quorumsensing (QS), which is an intercellular communication system mediated by the binding of signaling molecules to QS receptors such as LasR. In this study, a range of dihydropyrrolone (DHP) analogues were synthesized via the lactone-lactam conversion of lactone intermediates. The synthesized compounds were tested for their ability to inhibit QS, biofilm formation and bacterial growth of
The aerobic oxidation of pyrrolones catalyzed by Fe(OTf)3 to form reactive N-acyliminium ion intermediates that undergo nucleophilic additions to give the corresponding products is described.

The present disclosure is directed to compounds of formulas (I)-(VI), which are useful as modulators of USP19. The compounds are further useful in the inhibition of USP19 and the treatment of diseases or disorders associated with the inhibition of USP19. For instance, the disclosure is concerned with compounds and compositions for inhibition of USP19 and methods of treating diseases associated with the inhibition of USP19 (e.g., Parkinson's disease, Ewing sarcoma, and other metabolic diseases including muscle wasting and diabetes).

A three step, convergent synthesis of 4-aryl-3-pyrrolin-2-ones from a tetramic acid has been developed. The key transformation utilized a Suzuki-Miyaura cross-coupling reaction between a 4-tosyloxy-3-pyrrolin-2-one and an arylboronic acid. This work also provides access to 4-arylpyrrolidin-2-ones, cyclic analogs of gamma-aminobutyric acid (GABA). Hydrogenation of 4-(4'-chloro-phenyl)-3-pyrrolin-2-one proceeded smoothly to give baclofen lactam. (c) 2006 Elsevier Ltd. All rights reserved.
