    Synthesis of Both Enantiomers of a P-Chirogenic 1,2-Bisphospholanoethane Ligand via Convergent Routes and Application to Rhodium-Catalyzed Asymmetric Hydrogenation of CI-1008 (Pregabalin)
    摘要:
    Both enantiomers of a P-chirogenic 1,2-bisphospholanoethane ligand are synthesized via two convergent methods. The first method relies on the chiral alkylation of 1 -((-)-menthoxy)phospholaneborane using a s-BuLi/(-)-sparteine derived chiral base. Only one enantiomer of the catalyst could be synthesized via this method because only one antipode of sparteine is available in nature. The second route relies on the combination of methylphosphine borane and a chiral 1,4-diol. Either enantiomer of the ligand can be synthesized via the second route from the appropriate enantiomer of the 1,4-diol. Asymmetric hydrogenation using catalyst precursor 36 on acetamidoacrylic acid derivatives provided modest to good enantioselectivity (77-95% ee) under low H-2 pressure (30 psi). Asymmetric hydrogenation of Cl-1008 (pregabalin) precursors, 39 and 40, provided good enantioselectivities (92%) at high catalyst loading (1 mol %) and low pressure (30 psi). Enantiomeric excesses dropped sharply with catalyst loading at this pressure. Increasing the pressure of H-2 caused a significant increase in enantiomeric excess for low catalyst loading reactions. Several studies were undertaken to further investigate the enantioselectivity dependence on both pressure and catalyst loading.

  • NMR and X-ray crystallographic studies of unsymmetrical 25,26;27,28-dibridged para-tert-butyl calix[4]arene bisphosphites with a large “through-space” P–P coupling

    Three 25,26-bridged para-tert-butyl-calix[4]arene phosphites, 1–3, have been synthesized by linking two proximal phenolic oxygen atoms of para-tert-butyl-calix[4]arene to a P(OR) [R = 2,6-But2–4-Me-C6H2 (1), 2,6-Pri2-C6H3 (2) or 2,4-But2-C6H3 (3)] moiety. NMR spectroscopic data and X-ray crystallographic studies (1 and 2 only) show that the calixarene framework in 1 adopts a cone conformation, whereas in 2 and 3 it assumes a partial cone conformation. Unsymmetrical 25,26;27,28-dibridged para-tert-butyl-calix[4]arene bisphosphites 5–7 have been synthesized by the reaction of 25,26-bridged para-tert-butyl-calix[4]arene phosphite 1 with (R′O)PCl2 [R′ = 2,4-But2-C6H3 (5), 2,6-Pri2-C6H3 (6) or (1R,2S,5R)-(−)menthyl (7)]. NMR investigations (homonuclear 31P COSY) revealed an unprecedented “through-space” phosphorus–phosphorus coupling of 223–244 Hz for these unsymmetrical 25,26;27,28-dibridged para-tert-butyl-calix[4]arene bisphosphites. The molecular structure of unsymmetrical 25,26;27,28-bridged bisphosphite 5 was determined by X-ray crystallography; the two phosphorus atoms are in close proximity and the P⋯P distance (3.543(2) Å) is less than the sum of their van der Walls radii.

Variable-temperature (31)P NMR studies revealed that the biphenolic ligands are tropos even at low temperature. Only below 190 K was a coalescence observed; upon further cooling, two atropisomers were detected. The

    A library of 19 chiral tropos phosphorus ligands, based on a flexible (tropos) biphenol unit and a chiral P-bound alcohol (11 phosphites) or secondary amine (8 phosphoramidites), was synthesized. These ligands were screened, individually and as a combination of two, in the rhodium-catalyzed asymmetric hydrogenation of dehydro-alpha-amino acids, dehydro-beta-amino acids, enamides and dimethyl itaconate
    合成了一个基于柔性(对位)双酚单元和一个手性P结合醇(11个亚磷酸盐)或仲胺(8个亚磷酰胺)的19个手性对位磷配体的文库。在铑催化的脱氢α-氨基酸,脱氢β-氨基酸,酰胺和衣康酸二甲酯的铑催化的不对称氢化中,分别或以两种的组合筛选这些配体。通过使用配体,亚磷酸酯[4-P(O)2O]和亚磷酰胺[13-P(O)2N]的最佳组合,可以得到高达98%的脱氢α-氨基酸ee值。与单个配体以及亚磷酸酯[4-P(O)2O]和亚磷酰胺[13-P(O)2N]组合反应的动力学研究表明,亚磷酸酯尽管对映选择性较低,与相同的亚磷酸酯与亚磷酰胺的混合物相比,促进2-乙酰氨基丙烯酸甲酯和2-乙酰氨基doc酸甲酯的氢化速度更快,而仅亚磷酰胺的活性低得多。这样,通过降低亚磷酸酯/亚磷酰胺的比率(最佳比率为0.25当量的亚磷酸酯/1.75当量的亚磷酰胺)来优化反应,从而改善了产物对映体过量。还提出了一个简单的数学模型,以更好地
