Abstract
The invention comprises compounds of the formulae <FORM:0910600/IV (b)/1> where R is C1-5 alkyl, and <FORM:0910600/IV (b)/2> and a process for the production of L-(+)-glutamine characterized in that a g -ester of L-glutamic acid, the ester portion of which is derived from a C1-5 alkanol, and which may be prepared in situ, is treated with ammonia in the presence of carbon disulphide, and L-(+)-glutamine recovered from the reaction product by acidification. A C1-6 alkanol may be used as solvent.
