(+)-Goniothalamin has been synthesized by lipase catalyzed resolution of (1E)-1-phenylhexa-1,5-dien-3-ol using vinyl acrylate as acyl donor followed by ring closing metathesis of the formed (1R)-1-[(E)-2-phenylvinyl]but-3-enyl acrylate. The unreacted alcohol from the resolution, (1E,3S)-1-phenylhexa-1,5-dien-3-ol, was esterified non-enzymatically, and used for synthesis of (-)-goniothalamin. (C) 2003 Elsevier Ltd.

(+)-Goniothalamin 通过漆酶催化解析反应(使用(1E)-1-苯基六氢萘-1,5-二烯-3-醇,并以乙烯基丙烯酸作为酰基供体)合成,随后对形成的(1R)-1-[(E)-2-苯乙烯基]丁-3-烯基丙烯酸进行环闭转位反应。在解析过程中未反应的酒精即(1E,3S)-1-苯基六氢萘-1,5-二烯-3-醇,在非酶条件下进行了酯化,之后用于(-)-Goniothalamin 的合成。版权 © 2003 Elsevier Ltd. 保留所有权利。
