- PICOLINAMIDE AND PYRIMIDINE-4-CARBOXAMIDE COMPOUNDS, PROCESS FOR PREPARING AND PHAMACEUTICAL COMPOSITION COMPRISING THE SAME
-
Provided are picolinamide and pyrimidine-4-carboxamide compounds, a method for preparing the same, a pharmaceutical composition containing the same, and a medical use using the compound as an agent for preventing, regulating, and treating diseases related to regulation of glucocorticoids by using selective inhibitory activity of the compound for an 11β-HSD1 enzyme. The picolinamide and pyrimidine-4-carboxamide compounds of the present invention are selective inhibitors of human-derived 11β-HSD1 enzymes, and are useful in an agent for preventing, regulating, and treating diseases related to glucocorticoid regulation in which human- derived 11β-HSD1 enzymes are involved, for example, metabolic syndromes such as, type 1 and type 2 diabetes, diabetes later complications, latent autoimmune diabetes adult (LAD A), insulin tolerance syndromes, obesity, impaired glucose tolerane (IGT), impaired fasting glucose (IFG), damaged glucose tolerance, dyslipidemia, atherosclerosis, hypertension, etc.

- Nonproteinogenic amino acids: An efficient asymmetric synthesis of (S)-(-)-acromelobic acid and (S)-(-)-acromelobinic acid
-
An efficient synthesis of (S)-(-)-acromelobic acid (1) and (S)-(-)-acromelobinic acid (2) is described via asymmetric hydrogenation protocol. Asymmetric hydrogenation of dehydroamino acid derivative 23 using (R,R)-[Rh(DIPAMP)(COD)]BF4 catalyst followed by removal of the protective groups afforded (S)-(-)-acromelobic acid (1) in >98% ee. The key intermediate 23 was prepared from citrazinic acid (8). The dehydroamino acid derivative 33 required for the synthesis of (S)-(-)-2 was prepared from 2,5-lutidine (27), which upon hydrogenation using (S,S)-[Rh(Et-DuPHOS)(COD)]BF4 catalyst afforded (S)-(+)-34 in 93% yield and >96% ee. Removal of protective groups in (S)-(+)-34 afforded (S)-(-)-acromelobinic acid (2) in good overall yield.

- Asymmetric synthesis of (S)-(-)-acromelobinic acid
-
A total synthesis of (S)-(-)-acromelobinic acid 2, which was isolated from clitocybe acromelalga, was achieved via an asymmetric hydrogenation protocol. Dehydroamino acid derivative 12 was prepared from 2,5-lutidine 5 and subjected to asymmetric hydrogenation using (S,S)-[Rh(Et-DuPHOS)(COD)]BF4 to give the (S)-(+)-pyridylalanine derivative 13 in 93% yield and >96% e.e. Removal of the protecting groups in (S)-(+)-13 afforded (S)-(-)-acromelobinic acid 2.
