Cyclization of 4-thiazolidinone derivatives (2a-c) with various α–cyanocinnamonitriles afforded the corresponding thiazolopyridine derivatives (5a-r). Thiazolopyridine derivatives (5a,b ) are refluxed with acetic anhydride, and gave N,N-diacetyl amino derivatives (8a,b).}, keywords = {}, url = {https://absb.journals.ekb.eg/article_10835.html}, eprint = {https://absb.journals.ekb.eg/article_10835_57a4ea0cc4db195963839065b1fc7e80.pdf} }
