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.

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.
