Usage

Uses

1-(Phenylsulfonyl)pyrrole (1-phenylsulfonyl-1H-pyrrole) may be used in the synthesis of 1-(phenylsulfonyl)pyrrole-2-boronic acid, via lithiation of 1-(phenylsulfonyl)-pyrrole. It may be used for the synthesis of 1-phenylsulfonyl-1H-pyrrole-3-sulfonyl chloride derivatives, which affords sulfonamide derivatives by reaction with nitrogen nucleophiles.

General Description

1-(Phenylsulfonyl)pyrrole is a heterocyclic building block. 1-(Phenylsulfonyl) group serves as N-blocking and directing group in various organic syntheses.

Organic reactions in ionic liquids: A simple and highly regioselective N-substitution of pyrrole

In ionic liquids [Bmim][PF6] or [Bmim][BF4], pyrrole replaced the halogen atom of an alkyl halide to give the corresponding N-substituted pyrrole in excellent yield. Benzenesulfonyl chloride, p-methylbenzenesulfonyl chloride and benzoyl chloride reacted similarly with pyrroles to afford the N-substituted pyrroles in quantitative yield. Michael addition reaction of pyrrole with electrophilic olefins was completed in a highly regioselective manner to afford the N-alkylpyrroles.

Structural Basis of Metallo-β-lactamase Inhibition by N-Sulfamoylpyrrole-2-carboxylates

Metallo-β-lactamases (MBLs) can efficiently catalyze the hydrolysis of all classes of β-lactam antibiotics except monobactams. While serine-β-lactamase (SBL) inhibitors (e.g., clavulanic acid, avibactam) are established for clinical use, no such MBL inhibitors are available. We report on the synthesis and mechanism of inhibition of N-sulfamoylpyrrole-2-carboxylates (NSPCs) which are potent inhibitors of clinically relevant B1 subclass MBLs, including NDM-1. Crystallography reveals that the N-sulfamoyl NH2 group displaces the dizinc bridging hydroxide/water of the B1 MBLs. Comparison of crystal structures of an NSPC and taniborbactam (VRNX-5133), presently in Phase III clinical trials, shows similar binding modes for the NSPC and the cyclic boronate ring systems. The presence of an NSPC restores meropenem efficacy in clinically derived E. coli and K. pneumoniae blaNDM-1. The results support the potential of NSPCs and related compounds as efficient MBL inhibitors, though further optimization is required for their clinical development.
