  Enantioselective Syntheses of (+)-Sertraline and (+)-Indatraline Using Lithiation/Borylation–Protodeboronation Methodology

  摘要：

  The lithiation/borylation-protodeboronation of a homoallyl carbamate was applied to the synthesis of (+)-sertraline and (+)-indatraline. Due to the presence of the alkene, significant modifications of the methodology were required (use of 12-crown-4, TMSCI, H2O), or a solvent switch to CHCI3, to achieve high yields and high selectivities.

• Comprehensive Experimental and Theoretical Studies of Configurationally Labile Epimeric Diamine Complexes of α-Lithiated Benzyl Carbamates

  Different primary benzyl-type carbamates were deprotonated by sec-butyllithium in the presence of a tert-leucinol-derived bis(oxazoline) ligand. The resulting configurationally labile epimeric complexes equilibrated and one diastereomer was strongly favored in the equilibria. After dynamic thermodynamic resolution, the complexes could be trapped with different classes of electrophiles to yield highly enantioenriched secondary benzyl carb­amates. The stereochemical course of the substitution reactions was elucidated. High-level quantum chemical investigations were performed and allowed a prediction of both the favored complex and the enantiomeric excess that could be expected within the reactions.

• Enantioselective synthesis of (<i>R</i>)-tolterodine using lithiation/borylation–protodeboronation methodology

  The synthesis of the pharmaceutical (R)-tolterodine is reported using lithiation/borylation–protodeboronation of a homoallyl carbamate as the key step. This step was tested with two permutations: an electron-neutral aryl Li-carbamate reacting with an electron-rich boronic ester and an electron-rich aryl Li-carbamate reacting with an electron-neutral boronic ester. It was found that the latter arrangement was considerably better than the former. Further improvements were achieved using magnesium bromide in methanol leading to a process that gave high yield and high enantioselectivity in the lithiation/borylation reaction. The key step was used in an efficient synthesis of (R)-tolterodine in a total of eight steps in a 30% overall yield and 90% ee.

  报道了使用锂化/硼化-脱硼酸作为关键步骤合成药用（R）-托特罗定的方法。此步骤经过两种排列方式的测试：一个电中性芳基Li-氨基甲酸酯与一个富电子硼酸酯反应，以及一个富电子芳基Li-氨基甲酸酯与一个电中性硼酸酯反应。发现后者的排列比前者要好得多。通过在甲醇中使用溴化镁，进一步改进了方法，导致在锂化/硼化反应中获得高产率和高对映选择性的过程。关键步骤在总共八个步骤中以30%的总产率和90%的对映选择性高效合成了（R）-托特罗定。
• Cu(I)-catalyzed stereospecific coupling reactions of enantioenriched α-stannylated benzyl carbamates and their application

  日期：2008.9

  Enantioenriched α-stannylated benzyl carbamates were used in highly stereospecific coupling reactions employing Cu(I) as catalyzing transition metal. Acid chlorides and allyl bromide derivatives were used as electrophilic coupling partners. The reaction was applied in the synthesis of two highly enantioenriched indanoles and one enantioenriched tetraline via intramolecular cyclization reactions.
