Description and Uses
6-Methyl-5-hepten-2-one has a strong, fatty, green, citrus-like odor, and a bittersweet taste reminiscent of pear. May be prepared from oil of lemongrass or from citral by refluxing for 12 hours in aqueous solution containing K2C 03, and subsequent distillation and vacuum fractionation; from acetoacetic ester and methylbuten-3-ol-2 with aluminum alcoholate in Carroll’s reaction followed by pyrolysis of the ester.
6-Methyl-hepten-2-one is used in the synthesis of thyrsiferyl 23-Acetate which acts as an anti-leukemic inducer of apoptosis.
