Copper-catalyzed borylative cyclization of o-(cyano)phenyl propargyl carbonates leads to a highly efficient and regioselective synthesis of 3-boryl-1-naphthylamines. A cascade sequence involving the formation of allenyl boronates via borylcupration, debor

A gold-catalyzed oxidative cyclization of alkyne-nitriles using water or alcohol as the external nucleophiles has been developed. The catalytic system, featured with gold and Lewis acid dual catalysis, allows a facile synthesis of functionalized isoquinolin-1(2H)-ones and 1-alkoxy-isoquinolines with a wide structural diversity.

Gold(I)-catalyzed decarboxylation of propargyl carbonates: Reactivity reversal of the gold catalyst from π-Lewis acidity to σ-Lewis acidity

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.
Synthesis of naphthalene amino esters and arylnaphthalene lactone lignans through tandem reactions of 2-alkynylbenzonitriles

Tandem reaction of 2-alkynylbenzonitriles with a Reformatsky reagent turned out to be a novel and efficient approach toward 1-aminonaphthalene-2- carboxylates. Interestingly, with 2-(3-hydroxyprop-1-ynyl)benzonitriles as the substrates, a more sophisticat
