A direct, redox-neutral, highly atom-economical and metal-free aerobic method for the synthesis of multi-substituted olefins via simply coupling ammonium thiocyanate with activated ketones is described. A series of multi-substituted olefins could be easily and efficiently obtained in excellent yields by using low-toxicity and inexpensive ammonium thiocyanate as an amine and thiocyanate source, and
Compounds are provided that are modulators of the C5a receptor. The compounds are substituted dihydropyridines and are useful in pharmaceutical compositions, methods for the treatment of diseases and disorders involving the pathologic activtation of C5a receptors.
