variety of terminalalkenes were converted to the corresponding amides in yields of 25 to 86% in water via treatment with 1,3-dibromo-5,5-dimethylhydantoin, followed by reaction with molecular iodine and aq. NH3 (or amine) in one pot. This metal- and organic solvent-free protocol is not only suitable for styrene derivatives, but also, for the first time, works well on terminal aliphatic alkenes.

The oxidative copper‐catalyzed cross‐coupling of functionalized alkyl boronic esters with primary amides is reported. Through the identification of appropriate diketimine ligands, conditions for efficient coupling of both primary and secondaryalkyl boronic esters with diverse primary amides, including acetamide, have been developed.

The present invention is directed towards new chemical entities which primarily inhibit the human T-type calcium channels and differentially modulate other key ion channels to control cell excitability, and abnormal neuronal activity particularly involved in the development and maintenance of persistent or chronic pain, and / or neurological disorders. These novel compounds are useful in the treatment and prevention of neurological and psychiatric disorders and diseases in which these ion channels are involved. The invention is also directed towards pharmaceutical formulations comprising these compounds and the uses of these compounds.
