Vanilloid receptor ligands, pharmaceutical compositions containing them, process for making them and use thereof for treating pain and other conditions
The electrocarboxylation of α,α-dichloroarylmethane derivatives in the presence of CO2 was achieved, providing several α-chloroarylacetic acid derivatives with modest yields but high selectivity (chlorinated vs. non-chlorinated or dicarboxylic acid products). The obtained products were then involved in several chemical transformations, underlining their potential as versatile intermediates in synthetic
在 CO2 存在下实现了 α,α-二氯芳基甲烷衍生物的电羧化,提供了几种产率适中但选择性高的 α-氯芳基乙酸衍生物(氯化产物与非氯化产物或二羧酸产物)。获得的产品随后进行了多次化学转化,突显了它们作为合成化学中多功能中间体的潜力。基于控制实验和循环伏安法(CV)研究还提出了一种机制。
