An enantioselective synthesis of acyclic β-diaryl ketones and esters via 1,4-addition of arylboronic acids to β-aryl-α,β-unsaturated ketones or esters is described. The complex in situ prepared from [Rh(nbd)2]BF4 and chiraphos was fo

An asymmetric synthesis of a selective endothelin A receptor antagonist 1b is described. A highly substituted pyridine intermediate 11a was efficiently prepared via a mono-amination of inexpensive 2,6-dichloropyridine followed by a Vilsmeier formylation.
