Abstract

The formylation of  pyrrolo[1,2-a]pyrazines  containing alkyl, aryl, or hetaryl substituents in positions 1 and 6 of the heterocycle has been  studied.  It  has been shown that formylation of 1-phenyl- and 1-(2 thienyl)pyrrolo[1,2-a]pyrazine occurs selectively at the α-position of the pyrrole ring. In all of the remaining examples the reaction course depends on substituent, reagent ratio, and reaction time.
