Treatment of 2-[(dimethylamino)methylene]-3-oxobutanoates 9 or 10 with LiN(SiMe3)2 in the presence of RCOCl results in C-acylation. The resulting intermediate, without isolation, may be converted to 6-R 3-Carbethoxy-4-pyrones (e.g., 12) by H3O+ or to the corresponding pyridinones (e.g., 13) by NH4OAc. Typically, yields are 55-75% for R groups lacking acidic alpha or gamma protons and ca. 30% for R = Me2CH or MeCH = CH. Replacing 9 with MeCOC(= CHNMe2)SCH2Ph (from MeCOCH2SCH2Ph and Me2NCH(OMe)2 similarly affords 3(PhCH2S)-substituted products such as 29. Alkylation of the pyridinone anions produces mixtures of N- and O-substituted compounds, with the latter predominating; aminolysis of the isolated pyrones (R'NH2-HOAc, where R' = alkyl, Ar, HO, etc.) is the preferred route to the 1-R'-substituted pyridinones.
Iron-Catalyzed Aminolysis of β-Carbonyl 1,3-Dithianes: Synthesis of Stereodefined β-Enaminones and 3,4-Disubstituted Pyrazoles
A novel iron-catalyzed aminolysis of beta-carbonyl 1,3-dithianes with various amines including ammonia, primary and secondary amines, as well as hydrazine hydrate has been developed, leading to the synthesis of steleodefined beta-enaminones and 3,4-disubstituted pyrazoles in good to high yields.
