Treatment of silyl enol ethers and alk-1-ynes with SnCl4-Bu3N reagent followed by DBU, leads to cyclopent-2-enones, through <3+2> cycloaddition reactions; the initial carbon-carbon bond formation is carbometallation of alkynes, and the second step is a base-promoted intramolecular alkylation which reductively eliminates tin species (DBU = 1,8-diazabicyclo<5.4.0>undec-7-ene).
