Occurrence
Reported found in the rhizomes of Senecio kaempferi Seib.; the corresponding ester occurs naturally in waste wort. Also reported found in raspberries, wheat bread, cocoa, coffee, black tea, Arctic bramble, and green and roasted maté.
Uses
Chemical Intermediates.
Preparation
By the action of alkalis or bases on the ester of α-bromoisovaleric acid; by condensation of acetone with malonic acid or bromoacetic ester; by oxidation of mesityl oxide with sodium hypochlorite.
Definition
ChEBI: A methyl-branched fatty acid that is but-2-enoic acid bearing a methyl substituent at position 3.
Purification Methods
Crystallise the acid from hot water or pet ether (b 60-80o). [Beilstein 2 IV 1555.]
