In a new variation on the Fischer indole synthesis, readily available haloarenes are converted into a wide range of indoles in just two steps by halogen–magnesium exchange and quenching with di-tert-butyl azodicarboxylate, followed by reaction with aldehydes or ketones under acidic conditions. The protocol, which is readily extended to the preparation of indole isosteres, 4- and 6-azaindoles and thienopyrroles

Abstract Arylboronic esters add to di-tert-butyl azodicarboxylate under mild reaction conditions (at room temperature) to afford aryl-substituted hydrazine derivatives in good yields. The reaction tolerates a wide variety of functional groups.

[GRAPHIC]The addition of arylboronic acids 1 to azodicarboxylates 2 in the presence of a catalytic amount of a copper salt under mild reaction conditions gives aryl-substituted hydrazines 3 in high yields. The reaction is tolerant of a wide variety of functional groups.
