The unusual transformation represents the first example of activation and the reaction of the imidazole carbon atom. The proposed reaction mechanism was confirmed based on the DFT calculations A transition-metal-free postmodification of the Groebke-Blackburn-Bienaym (GBB) reaction for the synthesis of spiro[chromene-imidazo[1,2-a]pyridin]-3′-imines I (R = H, Me; R1 = Cy, t-Bu; R2 = H, Br; R3 = H, diethylaminyl; R4 = H, Br, Cl, NO2; R4R5 = -CH=CH-CH=CH-) was discovered. In this postcondensational modification, KOt-Bu acts as a base, which, after the isomerization of an alkyne moiety to allene, causes the next unique nucleophilic reaction of the imidazole carbon atom that results in spirocyclic structures I.
