一系列5,6-二取代的苯并[ b ]噻吩已被合成用于生物学评估。这些包括类色胺,褪黑激素和harmaline类型的类似物,在5位和6位均具有羟基,甲氧基,甲氧基甲氧基或异丙二烯二氧基。为了合成这些,制备适当的巯基愈创木酚,并与氯乙酰乙酸酯缩合为4-芳基硫代乙酰乙酸酯。当游离酚基被甲氧基甲基掩盖时,这些酮的环化效果最佳。然后将苯并[ b ]噻吩基乙酸酯转化为相应的酰胺,还原为色胺类似物,乙酰化为褪黑激素类似物,并环化为harmaline类似物。ñ还合成了乙酰色胺和1-甲基褪黑激素以进行比较。报告了褪黑激素类似物的初步生物测定结果,该结果显示了活性。

epoxide resolution process was rapidly developed that allowed access to multigram scale quantities of (R)-2-butyl-2-ethyloxirane 2 at greater than 300 g/L reaction concentration using an easy-to-handle and store lyophilized powder of epoxide hydrolase from Agromyces mediolanus. The enzyme was successfully fermented on a 35 L scale and stability increased by downstream processing. Halohydrin dehalogenases
