Also disclosed is a method for treating an opioid receptor-associated condition using such a compound. Further disclosed are two sets of thiazolidinone compounds of formula (I): (i) compounds each having an enantiomeric excess greater than 90% and (ii) compounds each being substituted with deuterium.
Highly Efficient Preparation of Amides from Aminium Carboxylates Using N-(p-toluenesulfonyl) Imidazole
N-(p-toluenesulfonyl)imidazole in the presence of triethylamine in DMF at 100 °C afforded the corresponding amides in good to excellent yields. N-(p-Toluenesulfonyl)imidazole proved to be a highly efficient coupling reagent for the preparation of numerous structurally diverse primary, secondary and tertiary amides.
在三乙胺的存在下,在 DMF 中,在 100 °C 下用 N-(对甲苯磺酰基)咪唑处理羧酸铵,得到相应的酰胺,收率良好至极好。N-(对甲苯磺酰基)咪唑被证明是一种高效的偶联剂,可用于制备多种结构不同的伯、仲和叔酰胺。
