  摘要：

  由（S）-和（R）制备非环酰胺化合物1（1（R，R），1（S，S）和内消旋体1（S，R））的三种立体异构体及其相应的四盐酸盐11。 -2-甲基哌啶。与原型化合物AMD3100相比，我们评估了它们对4型CXC趋化因子受体（CXCR4）的抑制活性，毒性性质以及对神经胶质瘤起始细胞（GIC）的影响。IC 50在人重组（CHO）细胞上测得的Rb值显示出非常相似的抑制活性，尽管AMD3100的K B较低，其中1（R，R）异构体的效力第二。所有化合物均显示出较低的心脏毒性，但与AMD3100相反，其最大非致死剂量约为2.0 mg / kg。CXCR4抑制剂对GIC的分化状态有影响，从而降低了成胶质细胞瘤多种形式的神经球中CD44 +细胞的百分比。此外，这些CXCR4抑制剂在免疫功能低下的小鼠中阻断了细胞引发原位肿瘤的能力。

  Chiral, nonracemic 2-substituted pyrrolidines and piperidines were prepared in high ee and moderate to good chemical yields in three steps from (R)-phenylglycinol and γ- or δ-chloroketones. The key step of the synthesis was the stereoselective reductive ring-opening of chiral bicyclic 1,3-oxazolidines prepared by condensation of (R)-phenylglycinol and the corresponding ketones.

  Compound 5 is a new α-amidoalkylation reagent for the asymmetric synthesis of 2-substituted piperidines. Its chiral auxiliary 3 is derived from camphoric acid and designed for an asymmetric induction mechanism featuring precomplexation as the decisive step for stereodifferentiation. Reagent 5 can smoothly be alkylated with various organometallic reagents after its activation by HCl-addition which presumably

  化合物5是用于2-取代的哌啶的不对称合成的新的α-酰胺基烷基化试剂。它的手性助剂3衍生自樟脑酸，设计用于不对称诱导机理，其特征在于预复合是立体分化的决定性步骤。试剂5在通过HCl加成活化后，可以用各种有机金属试剂平稳地烷基化，这大概会产生α-氯酰胺6。有机锌和有机铝化合物似乎能提供最佳结果，其非对映选择性最高，乙基化为77.8 / 2.2（7a / 8a），甲基化为87.7 / 12.3（7b / 8b）），96.5 / 3.5的丁基化（7C / 8C）和90.4 / 9.6为苯基化（7D / 8D的）5。可以通过除去手性助剂从α-酰胺基烷基化产物7a-d获得相应的旋光的2-取代的氯化氯化吡啶鎓9d-d，该除去可以通过用LiAlH 4还原或通过用KOH水解来完成。

  Total syntheses of enantiopure alkaloidal natural products (2S,6R)-dihydropinidine (as hydrochloride) and (2S,6R)isosolenopsins (as hydrochlorides) were achieved in four steps and in 80-82% total yields by using a synthetic strategy of the formation-cleavage of 1,3-oxazinane. (S)-Betti base was proved to be an excellent chiral auxiliary and a novel Pd/C catalyzed N-debenzylation straightforward to amine hydrochloride was developed in the presence of CH2Cl2.
