Zusammenfassung

Lithiumsalze der 1-Alkoxy-1-buten-3-ine lassen sich mit Säureanhydriden in guter Ausbeute zu 1-Alkoxy-1-alken-3-in-5-onen (1) acylieren, die durch alkalisch katalysierte Methanoladdition in Carbonylderivate von 3,5-Diketoaldehyden übergehen.

Abstract

Lithium salts of 1-alkoxy-1-butene-3-ynes are readily acylated in good yields by acid anhydrides to 1-alkoxy-1-alkene-3-yne-5-ones (1), which form carbonylderivates of 3,5-diketoaldehydes by base-catalyzed methanol addition.
