A practical, electrochemical method is developed for the direct dehydrogenative lactonization of C(sp2/sp3)–H bonds under external oxidant- and metal-free conditions, delivering diverse lactones, including coumarin derivatives with excellent regioselectivity. The scalable nature of this newly developed electrochemical process was demonstrated on a 40 g scale following an operationally simple protocol
The invention is directed to delta opioid receptor modulators. More specifically, the invention relates to tricyclic δ-opioid modulators. Pharmaceutical and veterinary compositions and methods of treating mild to severe pain and various diseases using compounds of the invention are also described.
