Linoleoyl chloride → (7Z,10Z)-hexadeca-7,10-dienoic anhydride

Participants

Reaction Steps

Finally, in a dry 2-necked, round bottomed flask, fixed with a separatory funnel, containing 17.93 g (60 mmol) of the prepared (9Z,12Z)-octadeca-9,12-dienoyl chloride, and side arm water condenser fixed with a dry receiving flask, is placed 7.64 g (72 mmol) of ammonium 2-aminopropanoate. The round bottomed flask is placed in an ice bath and the (9Z,12Z)-octadeca-9,12-dienoyl chloride is added drop wise. After addition is completed the mixture is shaken and the ice bath is replaced by a heating mantle. The flask is then heated until no more solution is dropping into the receiving flask. This crude distillate is then further fractionally distilled to yield 2-aminopropanoic (7Z,10Z)-hexadeca-7,10-dienoic anhydride.
