Twelve optically active-alkyl derivatives of ethyl N-diphenylmethy- lene glycinate are synthesized by alkylation of ethyl N-diphenylmethylene glycinate with alkylhalides in the presence of chiral phase transfer cata- lysts under solid-liquid two phase system at room temperature.These twelve optically active alkyl derivatives are easily hydrolyzed without racemiza- tion to give optically active ethyl amino esters.The optical yields range from 3.2%~96.6%.

u-Oxo bis [tetraphenylporphinatoiron (Ⅲ)], [TPPFe (Ⅲ)]_2O, was synthesized by passing chloro [tetraphenylporphinatoiron (Ⅲ)], TPPFe(Ⅲ)Cl, through a neutral Al_2O_3 chromatographic column, and was characterized by HPLC, IR, UV-Vis and elemental analysis. Just as TPPFe(Ⅲ)Cl, it has the properties of catalyzing the oxidation reaction of cyclohexane with PhIO under room temperature and atomsphere.In the oxidation reaction of cyclohexane, the yields of the oxidation products in CH_2Cl_2 and cyclohexane medium were 14.97% and 62.6%, respectively. In cyclohexane solvent, the quantities of products linearly correlated with the reaction time, and the reaction existed an induction period of about 3 hours, but both this linear correlation and induction period were absent in CH_2Cl_2. Compared with TPPFe(Ⅲ)Cl, [TPPFe·(Ⅲ)]_2O was more stable because it was difficult to be oxidized by oxidants. Above facts showed that [TPPFe(Ⅲ)]_2O could be used as a modal compound of cytochrome P-450 monooxygenase.

TPPFe(Ⅲ)Cl通过中性Al_2O_3色谱柱得到一个新化合物,它在HPLC中的保留时间比TPPFe(Ⅲ)Cl大得多,IR、UV-Vis和元素分析表明,这个新化合物是[TPPFe(Ⅲ)]_2~O.同TPPFe(Ⅲ)Cl一样,它具有在常温常压下催化碳氢化合物单充氧化的性质。[TPPFe(Ⅲ)]_2~O倦化下PhIO氧化环己烷的反应,在CH_2Cl_2和环己烷介质中,氧化产率分别为14.97和62.6%,高于TPPFe(Ⅲ)Cl作催化剂时的产率。在环己烷溶剂中,反应产率与反应时间呈线性关系,且反应有大约3小时诱导期。但在GH_2Cl_2溶剂中不存在反应产物与时间的线性关系,也不存在诱导期。与TPPFe(Ⅲ)Cl比较,[TPPFe(Ⅲ)]_2~O对氧化剂更稳定。上述事实表明,[TPPFe(Ⅲ)]_2~O能够作为细胞色素P-450的模型化合物。
