Abstract Racemic 4-hydroxy-3-isobornyl-5-methylbenzaldehyde was separated into particular enantiomers via transformation into diastereoisomeric Schiff bases by reaction with (R)-1-phenylethanamine. The absolute configuration of the products was determined on the basis of the X-ray diffraction data for camphanate derived from one enantiomer of 4- hydroxy-3-isobornyl-5-methylbenzaldehyde.
