  An efficient enantioselective synthesis of (R,R)-formoterol, a potent bronchodilator, using lipases

  摘要：

  0The potent beta(2)-adrenergic receptor agonist formoterol (R,R)-1 has been obtained in enantiomerically pure form by a convenient chemoenzymatic approach by coupling of epoxide (R)-6 with the unprotected primary amine (R)-9. Both chiral precursors have been prepared by enantiodifferentiation processes involving Pseudomonas cepacia (lipase PS) and Candida antarctica lipase (CALB), respectively. For the resolution of amine 9, we have found that utilization of triethylamine as non-reactive base enhances the reaction rate and the enantioselectivity of the process. The key coupling reaction of (R)-6 and (R)-9 has been conducted through derivatization of the amine with the labile trimethylsilyl group, which liberates the amino group of the resulting amino alcohol (R,R)-11 upon column chromatography purification. In this way, the overall approach is shorter than others previously described. (C) 2000 Elsevier Science Ltd. All rights reserved.

• Process for preparation of tamsulosin and its aralkylamine derivatives
  申请人：Jih Hwu Ru

  The present invention discloses a new process for the synthesis of tamsulosin and its aralkylamine derivatives, especially (R)-(−)-5-2-[2-(2-alkoxyphenoxy)ethylamino]propyl}-2-alkoxybenzenesulfonamides having the following formula 1 (where R 1 and R 2 represent C 1 -C 4 alkyl groups) and their hydrochloride thereof, and other various pharmaceutical used salts. Tamsulosin hydrochloride (R 1 =Et, R 2 =Me, in its hydrochloride salt form) is an antagonist of α-A adrenoceptors in the prostate. Tamsulosin•HCl occurs as white crystals, which melt with decomposition at approximately 230° C. It is sparingly soluble in water and in methanol, slightly soluble in glacial acetic acid and in ethanol, and practically insoluble in ether.

  Some pharmacologically active amines such as amphetamine, the isomeric o-, m- and p-methoxyamphetamines, 4-phenylbutan-2-amine and mexiletine, as well as their corresponding acetamides, have been prepared in high yields and with very high enantiomeric excesses. The method consists of the Candida antarctica lipase B (CAL-B)-mediated enantioselective acetylation of racemic amines using ethyl acetate

  ω-transaminases were tested for the synthesis of enantiomerically pure amines from the corresponding ketones employing D- or L-alanine as amino donor and lactate dehydrogenase to remove the side-product pyruvate to shift the unfavourable reaction equilibrium to the product side. Both enantiomers, (R)- and (S)-amines, could be prepared with up to 99% ee and >99% conversions within 24 h at 50 mM substrate concentration
