A base‐promoted chemoselective synthesis of 6a‐hydroxy‐6,6a‐dihydro‐1 H ‐thieno[3,4‐ b ]pyrrole‐3,3a(4 H )‐dicarboxylates, 5‐(2‐furylmethyl)‐6a‐hydroxy‐6‐oxo‐4,5,6,6a‐tetrahydropyrrolo[3,4‐ b ]pyrrole‐3,3a(1 H )‐dicarboxylates, and 5‐benzyl‐7a‐hydroxy‐1,4,5,6,7,7a‐hexahydro‐3a H ‐pyrrolo[3,2‐ c ]pyridine‐3,3a‐dicarboxylates starting from diazadienes and heterocycles containing an activated methine group has been developed. This transformations proceeds by Michael addition/5‐ exo cyclization sequence.
