Abstract
The reaction of p-nitrophenylsulfonylacetate with alpha,beta-unsaturat ed esters under solid-liquid phase transfer conditions (K2CO3/DMF/TEBA ) gave the unexpected Michael addition-rearrangement products. For exa mple, the reaction of p-nitrophenylsulfonylacetate with methyl methacr ylate resulted in the formation of 2-methyl-2-(p-nitrophenyl) glutarat e, presumably through the Michael adduct, which might rearrange to an intermediate, further lose sulfur dioxide and then led to the final pr oduct.
