摘要：

Gold(III)-catalyzed formal [3+2] cycloaddition of p-quinones with 1-phenylpropenes in ionic liquid, [EMIM][NTf2], enabled environmentally friendly, stereoselective synthesis of 2,3-dihydrobenzofuran neolignans in good yields. The gold catalyst/ionic liquid could be recycled at least five times.
