- Reaction of 2,2,6-trimethyl-1,3-dioxin-4-one with Imines
-
The reaction of 2,2,6-trimethyl-1,3-dioxin-4-one (diketene-acetone adduct) (1) with imines was investigated.Heating of the adduct 1 with N-(1-phenylethylidene)aniline (6a) gave 6-methyl-1,2-diphenyl-4(1H)-pyridone 7a.Similar treatment of N-benzylideneanil

- REACTION OF 2,2,6-TRIMETHYL-1,3-DIOXIN-4-ONE WITH SCHIFF BASE
-
Heating of 2,2,6-trimethyl-1,3-dioxin-4-one (1) with Schiff bases (2a-f) gave 2,3-disubstituted 6-methyl-1,3-oxazin-4-ones (4a-f).N-Benzylidene-tert-butylamine, under the similar condition, gave acetoacetamide derivative (3g) and acetylazetidinone derivative (5).
