Thiamin analogs were used to synthesize mono gold(I)-carbene derivatives in a single step under aqueous conditions. The resulting thiazolium gold(I)-carbenes catalyze 5-endo-dig carbocyclization of an acetylenic dicarbonyl compound in organic solvents and hydroalkoxylation of an allene in aqueous buffer.
