The reactions of N-methylmorpholinium 4-aryl(hetaryl)-5-cyano-2-oxo-1,2,3,4-tetrahydropyridine-6-thiolates with malononitrile and acetone in ethanol afforded substituted tetrahydropyridothienopyridinones. In the absence of acetone, tetrahydropyridothiopyranopyridinones were isolated as the major reaction products. The latter were also synthesized independently by the reactions of the above-mentioned thiolates with 2-amino-1,1,3-tricyanopropene. The structure of 2,4-diamino-10-(2-chlorophenyl)-3-cyano-5-imino-8-oxo-7,8,9,10-tetrahydro-5H-pyrido[2',3':2,3]thiopyrano[4,5-b]pyridine was established by X-ray diffraction analysis.

High throughput screening of the corporate compound collection led to the identification of a novel series of 2-amino-9-aryl-3-cyano-4-methyl-7-oxo-6,7,8,9-tetrahydropyrido[2',3':4,5]thieno[2,3-b]pyridine derivatives as selective PR agonists. Initial SAR exploration leading to potent and selective agonists 9 and 11, X-ray crystal structure of 9 bound to PR-LBD and preliminary developability data are described. (C) 2009 Elsevier Ltd.
