2‐benoxazoles were synthesized in high yields from acylamino alcohols and acylamino‐ phenols, respectively, with triphenylphosphine‐2,3‐dichloro‐5,6‐dicyanobenzoquinone (PPh3‐DDQ) as the dehydrating and activating reagent. The synthesis was accomplished under neutral conditions.
用三苯基膦-2,3-二氯-5,6-二氰基苯并醌(PPh 3 -DDQ)作为脱水和活化试剂分别从酰基氨基醇和酰基氨基苯酚分别以高收率合成了2-恶唑啉和2-苯并恶唑。该合成在中性条件下完成。
