An efficient synthetic protocol was developed for the formation of 2‐allylidene 1,3‐diones in very good yields via [3,3]‐sigmatropic rearrangement of O ‐propargyl β ‐enones. Good yields of highly functionalized substituted furan derivatives were synthesized from O ‐propargyl β ‐enones under gold‐catalysis via intramolecular cycloisomerisation.
