Abstract
NEW MATERIAL:An optically active or racemic α-hydroxyaldehyde of formula I (B is alkyl, alkenyl, alkynyl, or aralkyl, which may have functional groups; R is alkyl, alkenyl, alkynyl, aralkyl, or aryl, which may have functional groups), and an optically active or racemic aldehyde of formula II.
EXAMPLE: (R)-2-Hydroxy-2-phenylpropionaldehyde.
USE: Intermediate of medicines (e.g. atrolactamide) and pesticides.
PROCESS: The compound of formula I is prepared by reacting an optically active or racemic compound of formula III (A is aryl) with a Grignard reagent, and hydrolyzing the product.
