N1,N1,N2,N2-tetramethyl-N1,N2-bis(sulfo)ethane-1,2-diaminium chloride ([TMBSED][Cl]2) was synthesized as an acidic ionic liquid and characterized using FT-IR, 1H and 13C NMR, mass spectroscopy, TG, DTG and DTA techniques. This ionic liquid was employed as efficient catalyst for the extremely facile and efficient synthesis of dihydropyrrol-2-ones and functionalized tetrahydropyridines. One-pot f...

An extremely facile and efficient procedure which has been developed for the synthesis of dihydropyrrol-2-ones. One-pot four-component reaction of amines, dialkyl acetylenedicarboxylates and formaldehyde in the presence of N,N,N,N-tetramethylguanidinium acetate [TMG][Ac] in methanol at ambient temperature provides substituted dihydropyrrol-2-ones in good to high yields. The important aspects of...

A convenient synthesis of different types of polyfunctional dihydropyrrol-2-ones via one-pot four component reactions of formaldehyde, dialkyl acetylenedicarboxylates and amines, catalyzed by trichloroacetic acid (Cl3CCO2H) at room temperature has been investigated. The significant advantages of this synthetic method are mild reaction conditions, available and inexpensive material, short reacti...

Subarachnoid hemorrhage (SAH) is a stroke with high rates of mortality and morbidity. SAH-induced cerebral vasospasm can lead to ischemic injury or death and is a common complication of SAH. Recently there has been an accumulation of emerging evidence that oxidation of heme-derived bilirubin into bilirubin oxidation products (BOXes) may be involved in cerebral vasospasm. BOXes are produced by t...

an extremely facile and efficient procedure which has been developed for the synthesis of dihydropyrrol-2-ones. one-pot four-component reaction of amines, dialkyl acetylenedicarboxylates and formaldehyde in the presence of n,n,n,n-tetramethylguanidinium acetate [tmg][ac] in methanol at ambient temperature provides substituted dihydropyrrol-2-ones in good to high yields. the important aspects of...

Infection of implanted medical devices is one of the major causes of nosocomial infections. A significant proportion of the devices become colonized by bacterial biofilms, thus resulting in high morbidity and risk of mortality. This study focuses on the non-specific covalent attachment of potent quorum sensing (QS) and biofilm inhibiting compounds, furanones (FUs) and dihydropyrrol-2-ones (DHPs...
