NaSH in the construction of thiophene ring fused with N-heterocycles: A rapid and inexpensive synthesis of novel small molecules as potential inducers of apoptosis

A facile construction of a thiophene ring fused with N-heterocycles has been achieved via the reaction of NaSH with 2-chloro-3-alkynyl quinoxalines/pyrazines leading to novel 2-substituted thieno[2,3-b]pyrazine/quinoxaline derivatives as potential inducers of apoptosis. Some of them showed encouraging pharmacological properties when tested in zebrafish.

NaSH was used for the first time to construct the thiophene ring fused with N-heterocycles.Figure optionsDownload as PowerPoint slide
