摘要:
An organometallic complex of a tridentate bis(phosphine)-carbodicarbene ligand and a transition metal, is described. In some embodiments the ligand has the structure of Formula (I): The complexes are useful in methods of making an allylic amine carried out by reacting a 1,3-diene with a substituted amine in the presence of such an organometallic complex to produce by intermolecular hydroamination the allylic amine.
摘要:
Sphingosine 1-phosphate (S1P) is involved in hyper-proliferative diseases, such as cancer and vascular remodeling in pulmonary arterial hypertension. Inhibitors of sphingosine kinase 1 and 2 (SK1 and SK2), which catalyze the synthesis of S1P, may be useful anti- proliferative agents. We have synthesized a series of sphingosine-based inhibitors of SK and SK2. Also provided in this invention are compounds that activate SK1 which can be used in diseases such as fibrosis, where intracellular S1P is anti-fibrotic.
