ADDITION VON ALDEHYDEN AN AKTIVIERTE DOPPELBINDUNGEN, XXVII. MITTEILUNG : EIN EINFACHER WEG ZU 2-HYROXY-CYCLOPENTENONEN
Stetter, H.,Schlenker, W.
, p. 3479 - 3482 (1980)
A new, easy synthetic route to 2-hydroxy-3-alkyl-cyclopentenones starting from the thiazolium salt catalyzed addition of aldehydes to 1-acetoxy-3-buten-2-one is described.

3-Aryl-2-hydroxycyclopent-2-en-1-ones, when subjected to asymmetric oxidation, result in enantiomerically enriched 2-aryl-5-oxotetrahydrofuran-2- carboxylic acids. Electron-donating substituents in the para position of the phenyl ring increase the yield and decrease the enantioselectivity of the process. Georg Thieme Verlag Stuttgart.
Addition of Aldehydes to Activated Double Bonds, XXVIII. Preparations and Reactions of Alkoxy- and Acetoxy-2,5-diones
Stetter, Hermann,Mohrmann, Karl-Heinrich,Schlenker, Walter
, p. 581 - 596 (2007/10/02)
Thiazolium salt-catalyzed addition of aliphatic ether-aldehydes and pyrancarbaldehydes leads to corresponding 1-alkoxy-2,5-alkanediones 1-11 and pyranyl-1,4-alkanediones 28 - 47.In the same manner aldehydes react with 1-acetoxy-3-buten-2-one to give 1-acetoxy-2,5-alkanediones 12 - 19, which after saponification yield the 1-hydroxy-5-alkyl-2,5-pentanediones 20 - 27.
