In this study, chloroauric acid (HAuCl4) is used as a catalyst in water for the stereoselective cycloisomerization of various functionalized allenes to five- or six-membered oxygen- or nitrogen-containing heterocycles. Compared to traditional gold catalysts in organic solvents, this new catalytic system is more environmentally friendly, and the gold catalyst can be reused after complete conversion
