  6,7-bis(tert-butoxycarbonylmethoxy)-4-(hydroxymethoxy)coumarin 在 N,N-二异丙基乙胺 作用下， 以 四氢呋喃 、 二氯甲烷 为溶剂， 反应 2.17h， 生成 di-tert-butyl (2S,3S)-N-[6,7-bis(tert-butoxycarbonylmethoxy)coumarin-4-yl-methoxy]carbonyl-3-{3-[4-(trifluoromethyl)benzoyl]aminobenzyloxy}aspartate

  Synthesis of carbamate-type caged derivatives of a novel glutamate transporter blocker

  摘要：

  L-threa-beta-Benzyloxyaspartate (L-TBOA) and (2S,3S)-3-{3-[4-(trifluoromethyl)benzoylamino]benzyloxy}aspartate (L-TFB-TBOA) are potent nontransportable blockers for glutamate transporters. We synthesized a carbamate-type coumarin derivative of L-TBOA 3a as a caged blocker and compared 3a with the corresponding ester-type analogs 1. The carbamate 3a was less sensitive to photolysis than the ester I but was more stable in the aqueous solution. The [6,7-bis(carboxymethoxy)-coumarin-4yl]methylcarbonyl (BCMCMC) group exhibited good results both in photoreactivity and stability. Therefore, we examined photolysis of N-BCMCMC-TBOA 3b and N-BCMCMC-TFB-TBOA 4, which immediately released blockers to show glutamate uptake inhibition. (C) 2004 Elsevier Ltd. All rights reserved.
