Description Mercuric chloride mediated cyclization of tethered alkynedithioacetals has been established as a general route to five- and six-membered
carbocycles and heterocycles. Substitution at the alkyne terminus leads to preferential formation of five-membered rings, whereas unsubstituted
alkynedithioacetals give six-membered rings as the major products. Mercuric iodide interrupts the reaction at the intermediate dithioacetal
stage.
