Provided herein are compounds having activity against TTR related conditions, and pharmaceutically accepted salts and solvates thereof. Also provided are methods of using the compounds for inhibiting and preventing TTR aggregation and/or amyloid formation in the peripheral nerves, kidney, cardiac tissue, eye and CNS, and of treating a subject with peripheral TTR amyloidosis.
An efficient aza-Michael addition of amines to a variety of activated olefins was carried out under solvent free conditions using iodine-alumina as a catalyst at room temperature or under microwave irradiation (in case of solid) in high yield.

TiCl3(OTf) on silica gel surface and introduced as a non-hygroscopic Lewis acidcatalyst for C-N and C-C bond formation via Michaeladditionreaction. A variety of structurally diverse nitrogen nucleophiles including α-aminophosphonates, aliphatic and aromatic amines and imidazole were evaluated as Michael donors. Friedel–Crafts alkylation of indoles and pyrrole was also investigated through Michael addition
摘要 TiCl2(OTf)-SiO2 是通过将 TiCl3(OTf) 固定在硅胶表面上简单制备的,并作为非吸湿性路易斯酸催化剂引入,通过迈克尔加成反应形成 CN 和 CC 键。各种结构不同的氮亲核试剂,包括 α-氨基膦酸酯、脂肪族和芳香族胺以及咪唑被评估为迈克尔供体。在 TiCl2(OTf)-SiO2 作为催化剂存在下,通过迈克尔加成反应研究了吲哚和吡咯的 Friedel-Crafts 烷基化反应。反应在室温或 60 °C 下在无溶剂条件下进行,以高产率获得所需的迈克尔加合物。图形概要
