A practical air and moisture tolerant procedure for the preparation of 1,5-enynes from propargylic alcohols by the Bronsted acid catalyzed direct propargylic substitution of the hydroxy group with allylsilanes is described. Also, a straightforward sequential catalytic protocol for the synthesis of bicyclo[3.1.0]hexane derivatives, from readily available starting materials, is presented.
