Syntheses of Heterocyclic Compounds Involving Aromatic Lithiation Reactions in the Key Step

Abstract

Heteroatom-directed aromatic lithiation reactions for the syntheses of several heterocyclic ring systems and naturally occurring compounds which have not been synthesised or which have been synthesised only through considerably longer routes by the usual methods are reviewed in this article. 1.
