Cyclic acetals of glutamic acid-γ-semialdehyde, process for their production and use |
| abstract |
The invention is directed to cyclic acetals of glutamic acid-γ-semialdehyde of the formula ##STR1## in which A is an unsubstituted alkylene group having 2 to 3 carbon atoms or such an alkylene group substituted by 1 to 2 methyl groups and to a method of producing a compound of formula (I) by reaction of a compound of the general formula ##STR2## in which A is as defined above with hydrogen cyanide or a cyanide ion supplying compound, ammonia or an ammonium ion supplying compound and carbon dioxide or a carbonate ion supplying compound and basic hydrolysis of the reaction mixture obtained and to using the compound of formula (I) to produce D,L-proline. |
