Method for producing quinic acid derivative |
| abstract |
(57) [Summary] A quinic acid is contained in a raw material liquid containing quinic acid. General formula (I) characterized in that the compound is converted into a quinic acid ester by reacting with an alcohol in the presence of an acid or base catalyst, and then reacted with a ketone derivative or an aldehyde derivative in the presence of an acid catalyst. (Wherein R 1 and R 2 are the same or different and represent hydrogen, an alkyl group or an aryl group, and R 1 and R 2 together form a chain member of 2 to 7 which may have a side chain. Wherein R 3 represents an alkyl group, an alkenyl group or an aralkyl group), and a pharmaceutical intermediate obtained from the quinic acid derivative obtained by the production method. A method for producing a shikimic acid precursor and shikimic acid useful as a body. The quinic acid acetal (I) and the shikimic acid precursor and shikimic acid can be efficiently and inexpensively produced from quinic acid contained in natural products. |
