Abstract
NEW MATERIAL:An optically active or racemic aminal derivative of formula I (A is aryl group; R1 is alkyl, alkenyl, alkynyl or aralkyl group, including those having a functional group at the organic part).
EXAMPLE: 2-Propionyl-3-phenyl-1,3-diazabicyclo[3.3.0]octane.
USE: An intermediate for an agricultural chemical and medicine.
PROCESS: A glyoxylic acid derivative of formula II (R2 is alkyl group) is reacted with a Grignard reagent in the presence of a magnesium halide, preferably in a solvent, e.g. THF, to give a compound of formula III (R3 is R1 or aryl group which may be substituted optionally).
