## Abstract Dialkyl 2‐(alkylamino)‐4,9‐dihydro‐9‐oxocyclohepta[__b__]pyran‐3,4‐dicarboxylates are prepared in a one‐pot three‐component reaction of alkyl isocyanide, dialkyl acetylenedicarboxylate, and __α__‐tropolone (=2‐hydroxycyclohepta‐2,4,6‐trienone). The reaction proceeds smoothly at room tem
