Various 3-substituted chiral 1,2,4-oxadiazole-containing Fmoc-β 3- and α-amino acids were synthesized from FmoC-(L or D)-Asp(OtBu)-OH and Fmoc-L-Asp-OtBu, respectively, in three steps (i.e., condensation of an aspartyl derivative with different

Tetrabutylammonium fluoride (TBAF) was found to be a mild and efficient catalyst for the synthesis of 3,5-disubstituted-1,2,4-oxadiazoles. Using 0.1 - 1.0 equivalents of TBAF in THF for 1 - 24 h at room temperature, alkanoyl- and aroyloxyamidines were converted in high yield to the corresponding 3,5-disubstituted-1,2,4-oxadiazoles. A variety of R and R′ substituents were investigated.
