摘　　要：2-Oxazolines and 2-benoxazoles were synthesized in high yields from acylamino alcohols and acylaminophenols, respectively, with triphenylphosphine-2,3-dichloro-5,6-dicyanobenzoquinone （PPh3-DDQ） as the dehydrating and activating reagent. The synthesis was accomplished under neutral conditions.2-Oxazolines and 2-benoxazoles were synthesized in high yields from acylamino alcohols and acylaminophenols, respectively, with triphenylphosphine-2,3-dichloro-5,6-dicyanobenzoquinone （PPh3-DDQ） as the dehydrating and activating reagent.
