Abstract
The reaction of N-phthaloyl-L-leucine acid chloride (1) with isoeugenol (2) was
carried out in chloroform, and novel optically active isoeugenol ester derivative 3 as a chiral
monomer was obtained in high yield. Compound 3 was characterized by 1 H-NMR, IR, and
mass and elemental analysis and then was used for the preparation of model compound 5
and polymerization reactions. 4-Phenyl-1, 2, 4-triazoline-3, 5-dione, PhTD (4), was allowed
to react with compound 3. The reaction is very fast and gives only one diastereomer of 5 .
