A series of bisaryl imidazolidin-2-ones has shown to be selective and orally active 5-HT2C receptor antagonists
摘要:
Bisaryl cyclic ureas have been identified as high affinity 5-HT2C receptor antagonists with selectivity over 5-HT2A and 5-HT2B. Compounds such as 8 and 22 have shown oral activity in a centrally mediated pharmacodynamic model of 5-HT2C function in rodents. (c) 2005 Elsevier Ltd. All rights reserved.

Compounds of formula (I) in which R1, n, Z, R3 and R4 have any of the meanings given in the specification, are inhibitors of the serine protease Factor Xa and are useful in the treatment of thrombotic disorders.
Abstract Based on our previous work, a safer and more sustainable protocol for the synthesis of N-(2-Hydroxyethyl)anilines has been developed. The synthesis included the selective alkylation reaction of aniline with 2-chloroethanol in H2O, eliminating the need for any catalysts and solvents during synthesis. Comparing with our previous work, the salient features of this methodology are eco-friendliness
palladium‐catalyzed carbene insertion into C(sp3)−H bonds leading to pyrrolidines was developed. The coupling reaction can be catalyzed by both Pd0 and PdII, is regioselective, and shows a broad functional group tolerance. This reaction is the first example of palladium‐catalyzed C(sp3)−C(sp3) bond assembly starting from diazocarbonyl compounds. DFT calculations revealed that this direct C(sp3)−H bond functionalization

alkanolamines, that have both amines and alcohols as reactive functional groups. Achieving 100% selectivity for O-formyl and O-acyl protection of alkanolamines is one of the examples of such reactions. To avoid protection and deprotection steps and overcome this problem, a novel chemoselective, efficient, and simple protocol for functional group protection as O-formylation and O-acylation of alkanolamines and
