Participants

Reaction Steps

22.0 g (0.2 mol) of hept-4-in-1-al, 14 g (0.2 mol) of methyl vinyl ketone, 5.4 g (0.02 mol) of Cat. 1 and 12.6 g (0.12 mol) of triethylamine are brought together in the manner described in Example 26. After 12 hours' reaction time at a surrounding temperature of 80° C in a nitrogen atmosphere, the mixture is worked up in the manner described in Example 21. On subsequent fractionation, undec-8-ine-2,5-dione is obtained.
