The synthesis and selected transformation of some cyclopentanoid β-ketoximesulfone derivatives are reported. Utilization of the sulfone group to stabilize adjacent negative charge facilitates smooth alkylation. Subsequent 1,4-elimination of the sulfonyl moiety generates a vinyl nitroso species that is readily intercepted by lithium acetylides.
