Synthesis of New (E)‐2‐(1H‐Indole‐3‐ylcarbonyl)‐3‐heteroaryl‐acrylonitriles via Microwave‐Assisted Knoevenagel Condensation

open access: yesJournal of Chemistry, Volume 2017, Issue 1, 2017., 2017
Given the broad spectrum of biological uses of heteroaryl‐acrylonitrile derivatives, it is necessary to find simple methods to synthesize and diversify this family of compounds. We report a stereoselective synthesis of a series of new (E)‐2‐(1H‐indole‐3‐ylcarbonyl)‐3‐heteroaryl‐acrylonitriles (3a–3i) obtained from 3‐(cyanoacetyl)indole and heteroaryl ...
