Au-catalyzed cyclization of monopropargylic triols: An expedient synthesis of monounsaturated spiroketals
The gold-catalyzed cyclization of monopropargylic triols to form olefin-containing spiroketals is reported. The reactions are rapid and high yielding when 2 mol % of the catalyst generated in situ from Au[P(t-Bu) 2(o-biphenyl)]CI and AgOTf is e
