Synthetic approaches to the 2012 new drugs

New drugs introduced to the market every year represent a privileged structure for a particular biological target.

This review covers the synthesis of twenty-six NCEs that were launched or approved worldwide in 2012 and two additional drugs which were launched at the end of 2011. (C) 2014 Elsevier Ltd.
