Hydride-Induced Anionic Cyclization: An Efficient Method for the Synthesis of 6-H-Phenanthridines via a Transition-Metal-Free Process
摘要:
A novel procedure for hydride-induced anionic cyclization has been developed. It includes the reduction of a biaryl bromo-nitrile with a nucleophilic aromatic substitution (SNAr). A range of polysubstituted 6-H-phenanthridines were so obtained in moderate to good yield with good substrate tolerance. This method involves a concise transition-metal-free process and was applied to synthesize natural alkaloids.
Synthesis of Substituted 2-Cyanoarylboronic Esters
摘要:
[GRAPHICS]The synthesis of substituted 2-cyanoarylboronic esters is described via lithiation/in situ trapping of the corresponding methoxy-, trifluoromethyl-, fluoro-, chloro-, and bromobenzonitriles. The crude arylboronic esters were obtained in high yields and purities and with good regioselectivities.
The present invention provides compounds of Formula (I): wherein all variables are as defined in the specification, and compositions comprising any of such novel compounds. These compounds are biased agonists, or β-Arrestin agonists of the angiotensin II receptor, which may be used as medicaments.
