Shang, Rui,Ji, Dong-Sheng,Chu, Ling,Fu, Yao,Liu, Lei
supporting information; experimental part, p. 4470 - 4474 (2011/06/24)
Worth its salt: The palladium-catalyzed decarboxylative coupling of the cyanoacetate salt as well as its mono- and disubstituted derivatives with aryl chlorides, bromides, and triflates is described (see scheme). This reaction is potentially useful for the preparation of a diverse array of α-aryl nitriles and has good functional group tolerance.

Page/Page column 8, (2010/09/05)
The present application relates to cilazapril intermediates and processes for the preparation of cilazapril intermediates, including (S)-6,11-dioxo-1,2,3,4,6,11-hexahydro-pyridazino[1,2-b]naphthalazine-1-carboxylic acid and its salts.
Discovery and structure-activity relationships of trisubstituted pyrimidines/pyridines as novel calcium-sensing receptor antagonists
Yang, Wu,Ruan, Zheming,Wang, Yufeng,Van Kirk, Katy,Zhengping, Ma.,Arey, Brian J.,Cooper, Christopher B.,Seethala, Ramakrishna,Feyen, Jean H. M.,Dickson Jr., John K.
supporting information; experimental part, p. 1204 - 1208 (2009/12/25)
The trisubstituted pyrimidine 1 was identified through high-throughput screening as a novel calcium-sensing receptor (CaSR) antagonist. Small molecule CaSR antagonists and/or negative allosteric modulators have the potential to act as an anabolic agent for the treatment of osteoporosis. The investigation of structure-activity relationships around 1 resulted in the identification of 18c and 18d, which showed efficacy at promoting PTH release in vivo and exhibited improved potency and solubility over the original lead 1.
