Opioids as enantioselective organocatalysts

, 2012
The field of organocatalysis has rapidly expanded over the past decade. Advantages of organocatalysts over many metal-based catalysts include air and moisture stability, low cost and potential reduced environmental impact. Moreover, there is no possibility of leaching of metallic species into the product, an important concern in pharmaceutical ...
