Synthesis of dihydroindenofuran scaffold via a Pd-catalyzed 5-endo-trig cyclization/enolate O-alkylation cascade

Copper-mediated tandem reaction of β-ketoesters/ketones with tertiary amines for the synthesis of 2,3-dihydrofurans

A novel synthetic method of 2,3-dihydrofuran using β-ketoester and TMEDA as starting materials has been developed.

Regioselective synthesis of novel and diverse naphtho[1,2-b]furan-3-carboxamides and benzofuran-3-carboxamides by cascade formal [3 + 2] cycloaddition

The regioselective synthesis of diverse naphtho[1,2-b]furan-3-amides and benzofuran-3-amides was accomplished by the In(OTf)₃-catalyzed cascade formal [3 + 2] cycloaddition of 1,4-naphthoquinones or benzoquinones with β-ketoamides.
