Catalytic dearomative hydroboration of heteroaromatic compounds

Abstract

Abstract: This review offers a comprehensive discussion on literature concerning the development of catalytic protocols for the dearomative hydroboration of heteroaromatic compounds. The importance of selective dearomatization of heteroarenes, their remarkable applications along with the development of different catalytic methods and their synthetic scopes are emphasized. Graphic abstract: The dearomatization/aromatization process of pyridine motif enables dihydropyridine (DHP) derivatives to act as a key intermediate in deriving biologically active species, pharmaceuticals, organocatalyst and sophisticated reducing agents. This review offers a complete overview of recent development of catalytic protocols for the dearomative hydroboration of heteroaromatic compounds.
