An efficient synthesis of structurally complex allenylsilanes through gold-catalyzed coupling of propargyl esters with alkynylsilanes is described. DFT calculations support a stepwise pathway consisting of two 1,2-rearrangements (acyloxy and silyl). A preliminary study on the enantioselective version would demonstrate its feasibility (er up to 95:5).
