An efficient method for the preparation of β-amino-α,β-unsaturated carbonyl compounds is demonstrated. Bench-stable sodium 3-oxo-enolates were prepared from carbonyl compounds, and reacted with amines in the presence of an acid and a desiccant. DFT studie
Synthesis of stacked 'push-pull' acetylenes
Berger, Daniel,Wilhelm, Patrick,Neuenschwander, Markus
, p. 326 - 337 (2007/10/03)
In view of possible solid-state polymerizations of crystalline stacked 'push-pull'-acetylenes 1, a series of compounds 1 has been synthesized (Scheme 3), and the results of X-ray analyses of 'push-pull'-acetylenes 1d,e,f are discussed. Of these three compounds, methyl 2-morpholinoacetylene carboxylate (1d) is by far the best candidate giving crystals with nicely stacked molecules (Fig. 3), Even in this case, however, stacking parameters d = 4,12 A and a = 31,6°are too large for allowing solid-state polymerizations.
Additions of nucleophiles to 3-oxo-2,3-dihydrothiophene 1,1-dioxides. Formation of vinyl sulfides, thioacetals and enaminones

3-Oxo-2,3-dihydrothiophene 1,1-dioxide (la) was prepared by oxidation of the commercially available 3methoxythiophene with dimethyldioxirane. Some other substituted 3-methoxythiophene derivatives were oxidized as well. Although the yields of these reactio
