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.
