(E)-3-(triMethylaMMonio)acrylate Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden

Reaction of allylic alcohols with (E)-(carboxyvinyl)trimethylammonium betaine affords (E)-3-(allyloxy)acrylic acids, which on heating are transformed to γ,δ-unsaturated aldehydes via Claisen rearrangement/decarboxylation.

synthetische

Preparative Methods of (E)-(Carboxyvinyl)trimethylammonium Betaine: A mixture of 25.0 g of ethyl propiolate, 14 mL of dichloromethane, and 440 mL of water is cooled to 5 °C and 90 mL of an aqueous 25% solution of trimethylamine is added with vigorous stirring over a period of 30 min. The mixture is then warmed to 25 °C for 3 h. The aqueous layer is separated and washed three times with 100 mL of dichloromethane. The aqueous solution is concentrated in vacuo at 45 °C. When the residue gives the appearance of a wet solid, it is treated with 150 mL of dioxane and concentrated as described above. The dioxane treatment-concentration procedure is repeated three times. The resulting yellow solid is triturated with acetonitrile until a white solid is obtained (25 g, 76% yield).

l?uterung methode

Purification of (E)-(Carboxyvinyl)trimethylammonium Betaine: yellow impurities can be removed by trituration with acetonitrile to obtain a white solid. This is dried at 25 °C in vacuo (0.1 mmHg) for 14 h.
