, p. 5320 - 5323 (2014)
A novel gold-catalyzed synthesis of unsaturated spiroketals that addresses regioselectivity issues commonly reported in metal-catalyzed spiroketalization of alkynes is reported. The reaction sequence is regulated by an acetonide protecting group which und

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
