A cationic gold(I)-catalyzed decarboxylative etherification of propargyl carbonates to selectively produce propargyl ethers is reported. In the reaction the gold(I) catalyst shows a distinct σ-Lewis acidity rather than the commonly observed π-Lewis acidity, and thus catalyzes the decarboxylation of a variety of propargyl carbonates to give the corresponding propargyl ethers with high selectivity. This reaction represents a rare example of the tunable reactivity of cationic gold(I) complexes between σ-Lewis acidity and π-Lewis acidity.
Gold-catalyzed cyclization of 3-(2′-azidoaryl)-1-arylpropargyl carbonates or 3-aryl-1-(2′-azidoaryl)propargyl carbonates to produce quinolines

A gold-catalyzed cyclization of 3-(2′-azidoaryl)-1-arylpropargyl carbonates to generate substituted quinolines via a sequence of 3,3-rearrangement, 6-endo-trig cyclization and denitrogenation has been developed. Similar products could be obtained from 3-aryl-1-(2′-azidoaryl) propargyl carbonates under different gold catalytic conditions via a sequential 6-endo-dig cyclization, denitrogenation, and 1,2-H shift process.
