Comer, William T. published the artcileReaction of cyclopentanones with methylsulfinyl carbanion, Category: esters-buliding-blocks, the main research area is cyclopentanone methylsulfinylmethyl carbanion reaction; cyclopentenepentanoic acid derivative.
Methylsulfinylcarbanion (-CH2SOMe) reacts with cyclopentanone at room temperature to afford the unexpected δ-methylene-1-cyclopentene-1-pentanoic acid (I) in good yield. This reaction appears limited to cyclopentanones, with only low yields isolated from 2- and 3-methylcyclopentanones. Mechanistic considerations and some reactions of the dienoic acid are discussed.
Journal of Organic Chemistry published new progress about cyclopentanone methylsulfinylmethyl carbanion reaction; cyclopentenepentanoic acid derivative. 39495-82-4 belongs to class esters-buliding-blocks, name is Ethyl 5-methylhex-5-enoate, and the molecular formula is C9H16O2, Category: esters-buliding-blocks.
