A new ring expansion of 1-acyl-1-cyclobutanes to give 2-cyclopentanones and its application to the synthesis of 2-, 2,4-, or 2,5-substituted cyclopentanones were studied.

A new ring expansion of the title compounds catalyzed by an acid was studied.The reaction of 2-methyl-1-(1-methylsulfinyl-1-(methylthio)alkyl)cyclobutanol was regio- and chemoselective to afford 3-methyl-2-(methylthio)cyclopentanone derivative.
