An Efficient Formal Synthesis of (−)-Balanol by Using Ruthenium-Catalyzed Asymmetric Hydrogenation
摘要:
An efficient formal synthesis of (-)-balanol is reported. The ten-step sequence leading to a key precursor 4 features a highly stereoselective synthesis of the functionalized hexahydroazepine core through dynamic kinetic resolution of a racemic alpha -amido beta -keto ester using a ruthenium(II)-catalyzed hydrogenation reaction.
Design and synthesis of constrained analogs of LCRF-0004 as potent RON tyrosine kinase inhibitors
摘要:
New fused bicyclic lactam head groups as rigidified analogs of thieno[3,2-b] pyridine-based kinase inhibitor LCRF-0004 were designed and synthesized. Depending on the functionalities and the size of these bicyclic head groups, potent inhibitors of RON tyrosine kinase with various level of selectivity against c-Met tyrosine kinase were obtained.
