Abstract

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 of the substrate.
