  天然存在的非丙酮产乙酸原的拟态研究：非THF类似物导致对人类肿瘤细胞的显着选择性细胞毒性。

  摘要：

  开发了一类天然存在的非丙酮产乙酸原素的结构简化的类似物，其中一些非THF类似物对肿瘤细胞系显示出显着的细胞毒性，并且在人肿瘤细胞和正常细胞之间具有良好的选择性。由于去除了天然模板上带有THF环的手性中心，合成路线大大缩短。这种简化还提供了通过组合策略对这些模拟物进行并行综合的途径。Chiron方法通过容易获得的手性结构单元6a和/或6b（由L-抗坏血酸或D-甘露醇依次制得，而丁烯内酯中的一个由手性构成）引入了其余的立体异构中心（位于醚键的α位）。片段取自L-乳酸盐。所有四个非对映异构体非THF类似物2a-2d对HCT-8细胞系均表现出显着活性，并且在针对HT-29细胞系进行测试时发现了更好的分化。还发现，丁烯内酯和乙二醇亚基均在针对肿瘤细胞系的细胞毒性中起重要作用，而丁烯内酯部分上的10-取代的羟基和甲基的绝对构型对其活性不太重要。

  epoxide (up to 46% compared to 50% theoretical yield) along with high enantioselectivity (up to 99%) were obtained in most cases using catalyst 1. Further studies showed that catalyst 1 could retain its catalytic activity for six cycles under the present reaction conditions without any significant loss in activity or enantioselectivity. To show the practical applicability of the above synthesized catalyst

  合成了一系列基于许多非手性和手性连接基的手性聚合Co（III）-salen配合物，并在末端环氧化物的不对称水解动力学拆分中评估了它们的催化性能。明智地研究了该连接基的作用，发现在手性BINOL型聚合物Salen配合物1的情况下，未反应的环氧化物的催化剂反应性和对映选择性的增加，特别是在短和短的情况下。长链脂族环氧化物。在大多数情况下，使用催化剂1可获得良好的分离度，即未反应的环氧化物的收率高（高达50％的理论收率的46％），以及高对映选择性（高达99％）。进一步的研究表明，催化剂在当前的反应条件下，图1所示的催化剂可以保持其催化活性六个循环而没有任何活性或对映选择性的明显损失。为了显示上述合成催化剂的实际适用性，我们使用配合物1以中等收率和高对映选择性合成了一些有效的手性β-阻滞剂。DFT（M06-L / 6-31 + G ** // ONIOM（B3LYP / 6-31G *：STO-3

  the deacylation was studied. In addition, the rate of the spontaneous intramolecular migration of different acyl groups was determined for the intermediate 2-monoesters. The acyl group migration may diminish the apparent stereoselectivity of the two-step process if fast migrating acyl groups are used. It was found that the migration rate of different acyl groups differs by up to two orders of magnitude

  开发了可扩展的脂肪酶催化方法，通过酯的立体选择性裂解来动力学拆分长链1,2-链烷二醇对映体。研究了脂肪酶，反应介质，亲核试剂，温度和酰基结构对反应速度，脱酰反应的立体选择性和立体选择性的影响。另外，对于中间体2-单酯，确定了不同酰基的分子内自发迁移的速率。如果使用快速迁移的酰基，则酰基迁移可能会降低两步法的表观立体选择性。发现不同酰基的迁移速率相差最多两个数量级，对于乙酰基和异丁酰基而言更快，而对于丁酰基和苯甲酰基而言则慢得多。

  absolute configuration of 1,2-diols formed by a primary and a secondary (chiral) hydroxyl group can be deduced by comparison of the 1H NMR spectra of the corresponding (R)- and bis-(S)-MPA esters (MPA = methoxyphenylacetic acid). This method involves the use of the chemical shifts of substituents L1/L2 attached to the secondary (chiral) carbon, and of the hydrogen atom linked to the chiral center (C
