Silica gel-mediated rearrangement of allylic acetates. Application to the synthesis of 1,3-enynes

Article abstract of DOI:10.1039/c0cc00035c

Silica gel was found to efficiently promote the rearrangement of allylic acetates into their most stable regioisomers under microwave irradiation. The reaction is easy to perform and eco-friendly. This method was applied to the metal-free synthesis of 1,3-enynes.
