Improved syntheton sythesis |
| abstract |
The present invention is directed to improved synthesis of commercially important syntetone ACHBs starting from readily available 3-hydroxy-γ-butyrolactone. This reaction uses a single pot method without separation or purification of intermediates. This is advantageous over the methods used in the prior art, which use reagents and conditions that minimize undesirable byproducts and can easily be used on a commercial scale. The product is obtained in high yield and is easily purified to provide an excellent intermediate for further synthesis of pharmaceutically important active substances used in commercially important products such as L-carnitine and HMG-coA reductase inhibitor products such as Lipitor. . |
