One for all: The coupling of a range of nitrogen‐ and sulfur‐containing heteroaryl halides with five‐membered nitrogen‐, oxygen‐, and sulfur‐containing heteroaryl boronic acids were achieved in high yields with only 0.5 mol % of the single‐component nickel precatalyst [(dppf)NiCl(cinnamyl)] (dppf=1,1′‐bis(diphenylphosphanyl)ferrocene). The reaction demonstrates good functional group compatibility,

The invention provides novel substituted 3-pyridyl thiophenes and pharmaceutical compositions thereof. The invention also provides methods of use of substituted 3-pyridyl thiophenes, and pharmaceutical compositions thereof, as inhibitors of lyases, e.g., the 17α-hydroxylase-C17,20 enzyme. The invention further provides methods for the treatment of cancer in a subject, comprising administering a substituted 3-pyridyl thiophenes, or a pharmaceutical composition comprising a substituted 3-pyridyl thiophenes to a subject. The cancer can be, e.g., prostate cancer or breast cancer.

Compounds of formula (I) wherein R1 to R16, A. B and E are as defined in the claims and pharmaceutically acceptable salts and esters thereof, are disclosed. The compounds of formula (I) possess utility as tissue-selective androgen receptor modulators (SARM) and are particularly useful as medicaments in the treatment of prostate cancer and other AR dependent conditions and diseases where AR antagonism is desired.
Sequential one pot double C H heteroarylation of thiophene using bromopyridines to synthesize unsymmetrical 2,5-bipyridylthiophenes
present CH heteroarylation reactions between thiophene and variouslysubstituted bromopyridines. The objective was to synthesize unsymmetrical 2,5-bipyridylthiophenes. We studied the reaction conditions allowing to a sequential one-pot double CH heteroarylation, in a view to introduce two different pyridyl moieties at positions 2 and 5 of the thiophene ring using bromopyridines. 11 original unsymmetrical
