  Chemoenzymatic asymmetric synthesis of fluoxetine, atomoxetine, nisoxetine, and duloxetine

  摘要：

  The asymmetric synthesis of two well-known anti-depressant drugs, fluoxetine and duloxetine has been accomplished in a chemoenzymatic manner. The main highlight of the synthesis is the enantioselective cyanohydrin formation by a plant (R)-HNL (hydroxynitrile lyase). The enantiopure cyanohydrins are then synthetically manipulated into the above two drug molecules and two of their structural analogues, atomoxetine and nisoxetine. (C) 2013 Elsevier Ltd.

  3-Chloro-1-phenylpropan-1-ol and the corresponding butanoate, 3-chloro-1-phenyl-1-propyl butanoate, were kinetically resolved using lipase B from Candida antarctica catalysis by transesterification and hydrolysis respectively. The resulting chiral building blocks (S)- and (R)-3-chloro-1-phenylpropanol were converted into both enantiomers of the antidepressant drugs, Fluoxetine, Tomoxetine and Nisoxetine.

  transesterification process in hydrophobic solvents (diisopropyl ether, toluene and hexane) enhanced the reaction rate drastically and gave optimal yields with high enantioselectivity (>99%). Moreover, enantiopure 3-hydroxy-3-phenylpropanenitrile products have been converted via enantioconvergent routes into the (R)- and (S)-enantiomers of the important anti-depressants fluoxetine, tomoxetine, nisoxetine and norfluoxetine

  （±）-3-羟基-3-苯基丙腈的简便制备方法是通过在乙醇水溶液中用NaCN开环氧化苯乙烯。随后通过脂肪酶介导的酯交换反应动力学分离该物质，得到S-醇和R-乙酸酯具有出色的收率和高对映选择性，尤其是对于脂肪酶PS-C'Amano'II而言。还研究了溶剂和脂肪酶固定化的作用。有趣的是，在疏水性溶剂（二异丙基醚，甲苯和己烷）的酯交换过程中使用固定化脂肪酶可大大提高反应速率，并以高对映选择性（> 99％）获得最佳收率。此外，对映体纯的3-羟基-3-苯基丙腈产物已通过对映收敛途径转化为重要的抗抑郁药氟西汀，托莫西汀，尼索西汀和去氟西汀的（R）-和（S）-对映体。

• Synthesis and C-11 labeling of three potent norepinephrine transporter selective ligands ((R)-nisoxetine, lortalamine, and oxaprotiline) for comparative PET studies in baboons

  Three potent antidepressants, (R)-nisoxetine, lortalamine, and oxaprotiline, with high affinity and high selectivity for the norepinephrine transporter (NET) were synthesized and radiolabeled with C-11 via [C-11]methylation. The reference compounds and their corresponding normethyl precursors were synthesized via multi-step synthetic approaches. The radiochemical syntheses were performed by simple alkylation of the corresponding normethyl precursors with no-carrier-added [C-11]CH3I in DMF. After HPLC purification, (R)-[N-(CH3)-C-1]nisoxetine, [C-11]lortalamine, and [1 v C]oxaprotiline were obtained in 63-97% radiochemical yields, whereas (R)-[O-(CH3)-C-11]nisoxetine was obtained in 23-29% radiochemical yields due to substantial formation of the undesired N-[C-11]methylated byproduct (64-70%). These C-11 labeled tracers allowed us to carry out comparative studies of NET in baboons with positron emission tomography (PET) and evaluate their potential as PET tracers for imaging brain NET.

  Both enantiomers (R)- and (S)- 3-chloro- 1-phenyl- 1-propanol can be obtained conveniently by an efficient enzymatic resolution process. They can be converted via enantioconvergent routes into all enantiomers of the important antidepressants (R)- and (S)- Tomoxetine, Fluoxetine and Nisoxetine.
