Chemoenzymic Synthesis of Optically Pure 1,3,4-Oxadiazol-2(3H)-ones with Acaricidal Activity
摘要:
Both enantiomers of 5-[1-(4-isopropoxy)phenyl]ethyl-3-(2-chlorophenyl)-1,3,4-oxadiazol-2(3H)-one (1a), a new compound with high ovicidal activity against Tetranychus urticae (Koch), were synthesized starting from enzymatically prepared optically pure 2-[4-(isopropoxy)phenyl]propanoic acid (3). Laboratory tests have shown that the biological activity of the R isomer is at least 400-fold higher than that of the S form.
