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.

A series of new 2-aroyl-3,5-diaryltetrahydro-1,4-thiazine-1,1-dioxides (2) has been synthesized either from phenacylsulfonylacetic acids (1) or phenacylstyrylsulfones (3), which in turn are obtained from the substituted acetophenones or styrenes, respecti
