5-dimethyl-1,3-dioxane-2-yl)ethyl]amino acids (4a-s) in 9-65% yields or provide the intermediates N-[2-(5,5-dimethyl-1,3-dioxane-2-yl)ethyl]amino acid methylesters (3a-s) in 78-87% yields. The saponification of 3a-s provided 4a-s in 80-89% yields. Using a xylene-induced ear edema model, the anti-inflammatory activities of these newly synthesized anti-inflammatory agents were evaluated. The results
