Studies on Disease-Modifying Antirheumatic Drugs. IV. Synthesis of Novel Thieno(2,3-b:5,4-c')dipyridine Derivatives and Their Anti-inflammatory Effect.
The syntheses and anti-inflammatory activities of novel thieno[2, 3-b]pyridine and thieno[2, 3-b : 5, 4-c']-dipyridine derivatives are desrcibed. These compounds were designed by modification of the quinoline template of a new type of disease-modifying antirheumatic drug (DMARD), TAK-603, and prepared by the Friedlander reaction as a key reaciton. Their anti-inflammatory effects were evaluated using an adjuvant arthritis rat model. Most of the compounds which included a dithylamino moiety in the side chain had potent anti-inflammatory effect. In particular, ethyl 2-(diethylaminomethyl)-4-(3, 4-dimethoxyphenyl)thieno[2, 3-b : 5, 4-c']dipyridine-3-carboxylate (21) exhibitied more potent activity than TAK-603.

Abstract To discover novel fluorophores of solution and solid dual-state emission (DSE) materials, unique V-shape furo[2,3-b]furans have been designed and synthesized by a one-pot method for the first time and their photoluminescent properties have been explored in benzene, THF, DMF and DMSO, as well as in the solid state. As the best example, 2,5-bis(4-(9H-carbazol-9-yl)phenyl)-6a-amino-3a,6a-dihydrofuro[2

α‐Cyano ketones have been used for the first time as Michael donors in the construction of chiral spiro compounds. In the presence of only 2 mol‐% of a chiral multifunctional organocatalyst, chiral spiro[4H‐pyran‐oxindole] derivatives were prepared in excellent yields with good‐to‐excellent enantioselectivities. This method provides a new approach to the synthesis of chiral spirocyclic oxindoles.
