In this focus article, the recent syntheses of various (hetero) aromatic/macrocyclic
molecules/scaffolds such as (thia) calixarenes, iptycenes,[poly](aza) arenes, 2, 2 …

Herein we disclose a silver-catalyzed [3+ 3] 1, 3-dipolar cycloaddition reaction of
trifluorodiazoethane with glycine imines. This reaction exhibits manifold remarkable …

A novel copper-catalyzed cascade cyclization reaction between enamines and electron-
deficient terminal alkynes has been developed. The reaction provides a new and efficient …

5, 7-Dimethoxy-8-(3, 6-diphenylpyridin-2-yl) coumarins were obtained from 5, 7-
dimethoxycoumarins and 3, 6-diphenyl-1, 2, 4-triazines via the protocol comprising aromatic …

Two tandem processes involving the cycloaddition of benzynes have been developed for
the synthesis of polyaromatic hydrocarbons. Benzynes react with fluorene-derived alkenes …
