catalysed reaction of 2-phenyl-4,4-dimethyl-2-oxazolin-5-one (1) with the ethylester of DL-alanine (2) in CCl4, to give the ethylester of N-(N′-benzoyl-α-amino-isobutyryl)-DL-alanine (3) is investigated. Within the range of concentrations employed, the reaction follows the rate equation ν = ko + k[monomer] [oxa] [ester], where ko is the specific rate constant of the uncatalysed reaction, and k′ is
乙酸催化的2-苯基-4,4-二甲基-2-恶唑啉-5-酮(1)与DL-丙氨酸的乙酯(2)在CCl 4中反应的动力学行为,得到乙酯研究了N-(N'-苯甲酰基-α-氨基-异丁酰基)-DL-丙氨酸(3)的结构。在所用浓度范围内,反应遵循速率方程ν= k o + k [单体] [oxa] [酯],其中k o是未催化反应的比速率常数,k '是催化反应的比速率常数反应。
