  Direct Catalytic Asymmetric Synthesis of Cyclic Aminals from Aldehydes

  摘要：

  A highly enantioselective Bronsted acid catalyzed direct synthesis of cyclic aminals from aldehydes has been developed. The methodology has been applied to the first asymmetric synthesis of several anti hypertensive aminal drugs including (R)-Thiabutazide.

  various immobilized chiral stationary phases (CSPs) have been developed. The immobilized CSPs have opened up possibilities not only maintaining the high chiral recognition abilities as well as corresponding coated ones but also affording high durability to various mobile phase. This report directed to investigate enantioseparation of recently launched four immobilized CSPs with cellulose and amylose

  迄今为止，已经开发了各种固定化手性固定相 (CSP)。固定化的 CSP 不仅为保持高手性识别能力和相应的涂层能力开辟了可能性，而且为各种流动相提供了高耐久性。本报告旨在研究在正相液相色谱条件下最近推出的四种具有纤维素和直链淀粉骨架的固定化 CSP 的对映体分离。将它们的手性识别能力与之前开发的六种固定化 CSP 进行了比较。特别是，我们专注于手性识别的互补性。其中，直链淀粉三（3-氯-5-甲基苯基氨基甲酸酯）CSP，即CHIRALPAK IG，对各种外消旋体显示出显着的手性识别能力。正如预期的那样，研究的固定化 CSP 对各种流动相具有显着的耐久性，而相应的涂层 CSP 由于不可逆的降解而无法运行。利用不受限制的溶剂相容性，一些外消旋体的手性分离选择性得到改善。
