Abstract
NEW MATERIAL:An optically active or racemic glyoxylic acid derivative of formula I (A is aryl group; R is alkyl group).
EXAMPLE: 2-Carbomethoxy-3-phenyl-1,3-diazabicyclo[3.3.0]octane.
USE: An intermediate for an agricultural chemical and medicine, capable of synthesizing an α-hydroxyaldehyde which is an intermediate for Atrolactamide used as a medicine.
PROCESS: A glyoxylic ester or its hemiacetal is reacted with a compound of formula II in a solvent, e.g. benzene or toluene, to give the compound of formula I. The reaction is preferably carried out while removing the formed water by azeotropic distillation.
