Ionic liquid N-ethylpyridinium hydrogen sulfate as an efficient catalyst for designing indole scaffolds and their antimicrobial behavior
Ionic liquid N-ethylpyridinium hydrogen sulfate has been prepared, characterized and used as an efficient recyclable catalyst for the synthesis of a series of indoles and bis(indolyl)methanes. Latter have been further explored for their potential antimicrobial activity against E coli and Bacillus. The ionic liquid used was recycled in the end and its recovery was facilitated b...

N,N,N,N-Tetramethylguanidinium acetate as an efficient and reusable ionic liquid catalyst for the one-pot synthesis of dihydropyrrol-2-ones
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...
