Synthesis of 2-acylfurans from 3-(1-alkynyl)-2-alken-1-ones via the oxidation of gold-carbene intermediates by H2O2

An efficient approach to 2,4,5-trisubstituted 2-acylfurans is described: treating 3-(1-alkynyl)-2-alken-1-ones with AuCl3 in DCM at rt in the presence of H2O2 afforded good yields of 2-acylfurans.

CuOTf/TfOH-mediated tandem reaction of conjugated ene-yne-ketones: Synthesis of novel spiro dihydrofurans

CuOTf/TfOH-mediated cascade cyclization-coupling-electrophilic substitution of conjugated ene-yne-ketones in DCE at 25 °C provided novel spiro dihydrofurans in 32–83% yield. The experimental results demonstrated that substituent group R3, which

AgOTf/I2-Mediated Cyclization/Cross-Coupling/Isomerization of Enynones with Phosphorus Ylides: An Expedient Route to Stereoselective Synthesis of (E)-2-Alkenylfurans

Ag(I)-catalyzed cascade reactions involving enynone cyclization and cross-coupling with phosphorus ylides have been achieved for the first time. Subsequent treatment of the reaction mixture with I2 afforded the corresponding (E)-α-alkenylfurans in 73-95%

Facile synthesis of cyanofurans via Michael-addition/cyclization of ene-yne-ketones with trimethylsilyl cyanide

We have developed a Michael-addition/cyclization procedure between ene-yne-ketones and TMSCN under metal-free conditions. A wide range of cyanofurans was delivered in high yields, which could be further transformed to a series of furo-furanimines, furo-pyridazines or carboxamido-furans. In addition, deuterium-labeling experiments have been conducted to clarify the reaction pathway.
