Significance

A highly efficient protocol for the direct olefination of sp³ C-H bonds was developed. In this reaction, strongly electron-deficient amides serve as directing groups. The method could be applied to a wide variety of substrates, including even cyclopropyl methylene C-H bonds and compounds containing α-hydrogen atoms.

Comment

The scope of the Mizoroki-Heck ­reaction has been considerably enlarged with this method. Now, not only sp² C-H bonds but also sp³ C-H bonds can be efficiently and selectively olefinated giving an easy and straightforward ­access to variously functionalized lactams.
