  Synthetic Applications of Baylis-Hillman Chemistry: An Efficient and Solely Stereoselective Synthesis of (E)-.ALPHA.-Methylcinnamic Acids and Potent Hypolipidemic Agent LK-903 from Unmodified Baylis-Hillman Adducts

  摘要：

  通过在室温下用I2/NaBH4试剂系统还原未改性的Baylis-Hillman加合物（甲基-3-羟基-3-芳基-2-亚甲基丙酸甲酯），然后进行水解，在单罐中实现了（E）-α-甲基肉桂酸的高效且完全立体选择性合成。这种方法的有效性已在1-[p-(肉豆蔻氧基)-α-甲基肉桂酰]甘油（LK-903）的全合成中得到证实，这是一种高活性的降血脂剂。

  An efficient one-pot stereoselective synthesis of trisubstituted (E)-2-methylalk-2-enoic acids has been accomplished by treatment of unactivated Baylis-Hillman adducts, 3-hydroxy-2-methylencalkanoates, with Al-NiCl2-6H(2)O in methanol at room temperature followed by hydrolysis. The method has been applied to the synthesis of three important insect pheromones, (4S,2E)-2,4-dimethyl-2-hexenoic acid, (+)-(S)-manicone and (+)-(S)-normanicone. (c) 2006 Elsevier Ltd.

  A simple and convenient stereoselective synthesis of [E]-alpha-methylcinnamic acids via the nucleophilic addition of hydride ion from sodium borohydride to methyl 3-acetoxy-3-aryl-2-methylenepropanoates followed by hydrolysis and crystallization is described. Efficacy of this methodology in the synthesis of [E]-p-(myristyloxy)-alpha-methylcinnamic acid, an active hypolipidemic agent, and [E]-p-(carbomethoxy)-alpha-methylcinnamic acid, a valuable synthon for an orally active serine protease inhibitor, is also demonstrated.

  An efficient and solely stereoselective synthesis of (E)-α-methylcinnamic acids has been accomplished in single pot by reduction of the unmodified Baylis–Hillman adducts, methyl-3-hydroxy-3-aryl-2-methylenepropanoates with I2/NaBH4 reagent system at room temperature followed by hydrolysis. The efficacy of this method has been proved in the total synthesis of 1-[p-(myristyloxy)-α-methylcinnamoyl]glycerol, LK-903, a highly active hypolipidemic agent.
