The third epimer, having d-Ala-4 had t-c-t-t-c-t amide configurations in the crystal, a type-VI beta-turn for residues 1-4 as observed in the first epimer, and in CDCl(3) existed in three conformers, of which the major one was similar to that in the crystal but different from that of RA-VII in solution.

    With the aim of obtaining compounds with strong antitumor activity and weak toxicity, we have synthesized a series of alkylethers, fatty acid esters, benzoates and other derivatives of RA-V, an antitumor cyclic hexapeptide discovered in Rubiae Radix, and examined their antitumor activities against P-388 lymphocytic leukemia. It was found that the introduction of C1 and C6 chains (hydrophobic coefficient log P=about 3.2 and 5.8, respectively) on the phenol moiety of RA-V gave the most desirable compounds in terms of antitumor activity and toxicity. The caproic ester of RA-V, the n-hexylether of RA-V and RA-VII (C1) also exhibited strong antitumor activity against other experimental tumors (L-1210 lymphocytic leukemia, B-16 melanoma and MM2 mammary carcinoma).

    In order to obtain a key compound (22a") for synthesis of RA-VII (1) and deoxybouvardin (2), construction of the 14-membered ring system was performed by means of thallium trinitrate-mediated oxidation of the tetrahalogeno amides 5-7. The dibromo dichloro amide 6 or the bromo trichloro amide 7 gave a natural type of 14-membered ring dienone (23a or 23c), whereas the tetrabromo amide 5 gave an unnatural type of product, 19a. The formation of the latter product 19a could be understood on the basis of energy calculations on plausible intermediates 26a-c and 27a-c in the transition state in the oxidaive coupling reaction. Compound 23a was further converted to 22a" through conventional procedures (aromatization; methylation; catalytic hydrogenation). This intermediate was readily converted to 1 and 2. Thus, total synthesis of RA-VII (1) and deoxybouvardin (2) was achieved for the first time.
    为了获得合成RA-VII(1)和去氧布瓦丁(2)的关键化合物(22a"),通过三硝酸铋介导的氧化反应对四卤酰胺5-7构建了14元环体系。二溴二氯酰胺6或溴三氯酰胺7产生了一种天然类型的14元环二烯酮(23a或23c),而四溴酰胺5则产生了一种非自然的产物19a。产物19a的形成可以通过对氧化偶联反应中可能的过渡态中间体26a-c和27a-c进行能量计算来理解。化合物23a通过常规程序(芳构化;甲基化;催化氢化)进一步转化为22a"。该中间体可以很方便地转化为1和2。因此,RA-VII(1)和去氧布瓦丁(2)的总合成首次得以实现。
