Treatment of gamma-(tert-butyldimethylsiloxy)- or gamma-(trimethylsiloxy)allenes bearing various groups at the ether carbon with N-iodosuccinimide resulted in the formation of iodocyclization products, 1-iodo-1-(tetrahydrofuran-2'-yl)ethenes, in good yields and with high selectivity for the cis diastereomer.
