The (R)-2-((R)- 1-ethoxy- 1--oxo-4-phenylbutan-2-ylamino)-6-(2,2,2-trifluoroaeetamido)hexanoic acid (LA2) was obtained by Michael addition from 3-benzoyl ethyl acrylate with (S)-2-amino--6-(2,2, 2- trifluoroacetamido) hexanoic acid in the presence of tributylamine triflate, followed by reduction with Pd/C. The ratio of S-LA/R-LA2 can reach 84:16, and the total yield is 38.8%. This synthetic route is suitable for large scale manufacture.
