Carbo-and heterocycles frequently serve as crucial scaffolds in drugs, natural products, fine
chemicals, and biologically and pharmaceutically active compounds. Consequently, the …

The review is summarized and systematized the published data on the multicomponent
reactions of ethyl trifluoroacetoacetate, carbonyl compounds (aldehydes and ketones), and …

We report herein an unprecedented Cu (II)-catalyzed divergent synthesis of naphthofurans
and benzochromanes from 2-naphthols, N, N-dimethylethanolamine, and methylene-3, 4 …

A formal (3+ 2) cycloaddition of 1, 4-enediones with 2-naphthols was established under the
catalysis of trifluoromethanesulfonic acid as an organocatalyst, leading to the efficient …

Indole structural motifs are ubiquitous in natural products, pharmaceuticals, agrochemicals
and functional materials. The immense importance of the indole moiety, especially in the …

A novel [2+ 1+ 3] cyclization reaction for the synthesis of 2-aryl-4-quinolinecarboxylates from
aryl methyl ketones, arylamines, and 1, 3-dicarbonyl compounds has been established. This …

The first sequential acid-catalyzed propargylation/base-mediated aza-cycloisomerization
between indolyl-benzimidazoles and propargylic alcohols is described. This protocol …

Herein, we reveal an unprecedented domino annulation of N-benzyl-acrylamides with 1, 3-
dicarbonyls for the assembly of fused tricyclic alkaloid frameworks incorporating a spirocycle …

Benzofurans have intrigued both pharmaceutical researchers and chemists owing to the
medicinal usage of their derivatives against copious disease-causing agents (ie, bacteria …

An efficient selenylative cyclization of aryl-alkynones with diselenides in the presence of iron
