| titleOfInvention | Preparation of optically-active mevalonic ester |
| abstract | PURPOSE: To obtain simply the titled compound useful as an intermediate for synthesizing various optically-active organic compounds, by reacting inexpensively obtainable optically-active mevalonolactone and its derivative as a raw material with a lower alkyl alcohol in the presence of a basic catalyst. n CONSTITUTION: An optically-active mevalonolactone shown by the formula I (R is H, or OH-protecting group) obtained by microbial oxidation of 3-methyl-pentane-1,3,5-triol and its derivative [e.g., optically-active (S)-mevanonolactone, etc.] is reacted with a lower alkyl alcohol shown by the formula R'OH (R' is 1W5C lower alkyl) in the presence of a basic catalyst (preferably basic ion exchange resin or ammonia) to obtain an optically-active mevalonic ester derivative [e.g., (S)-mevalonic acid methyl ester, etc.] shown by the formula II. Unreacted mevalonolactone or its derivative is reusable for esterification reaction. n COPYRIGHT: (C)1985,JPO&Japio |
