使用简单的密封两室系统实现了异位生成一氧化碳 (CO) 及其在钯催化的羰基化反应中的有效结合的新技术。CO 的异位生成是通过钯催化的叔酰氯脱羰使用源自 Pd(dba)(2) 和 P(tBu)(3) 的催化剂产生的。使用新戊酰氯作为 CO 前体的初步研究为仅使用 1.5 当量的 CO 对 2-吡啶基甲苯磺酸酯衍生物进行氨基羰基化提供了另一种方法。 酰氯 CO 前体的进一步设计导致开发了一种新的固体、稳定、并且易于处理用于化学转化的 CO 源。这种 CO 前体的合成也为后期安装同位素碳标记的酰氯以随后释放气态 [(13)C]CO 提供了切入点。结合旨在应用 CO 作为限制剂的研究,该方法提供了高效的钯催化氨基羰基化,CO 结合率高达 96%。异位生成的 CO 和双室系统在几种药物化合物的合成中进行了测试,所有这些化合物都被标记为 [(13)C] 羰基对应物,基于限制 CO 的产率从良好到极好。
