Abstract

Since the pioneering work by Gilman and Wittig, 1 the directed ortho metalation reaction has been widely used as a powerful and efficient method for regioselective functionalization of aromatic compounds. 2 Various directing groups have been employed for facilitating the deprotonation of arenes, and various strong bases such as alkyllithiums or lithium dialkylamides have been employed. The ester group has been regarded as an important ...
