An oxa-[2,3] sigmatropic rearrangement involving arynes is reported featuring the umpolung of ketones, where the C=O bond polarity is reversed. The in situ-generated sulfur ylides from β-keto thioethers and arynes undergo efficient rearrangement allowing the facile and robust synthesis of functionalized enol ethers in high yields and excellent functional group compatibility. Preliminary mechanistic studies rule out the possibility of Pummerer-type rearrangement operating in this case.

β-Keto vinylic sulfones, the key building blocks for the synthesis of the title compounds, were prepared by two different routes. NaBH4 reduction of these compounds afforded β-hydroxy vinylic sulfones which were dehydrated with acetic anhydride

The synthons, phenacylthio/sulfonyl acetates (III and IV) for the synthesis of title compounds VI, VII and VIII have been obtained by two different methods starting from phenacylbromide (I) and thioglycollic acid or from I and thioglycollates.The cyclocon
