Free carboxylic acids are converted into amides in moderate to high yields in the presence of a stoichiometric amount of trimethylaluminium and amines at 90 ËC after 1 hour.
自由羧酸在三甲基铝和胺的存在下,以适中至高产率,在90摄氏度下经过1小时后转化为酰胺。

spread worldwide with a previously unknown virulence. To date, no specific antivirals treatments nor vaccines are available against this important pathogen. Starting from the structures of two antiviral hits previously identified in our research group with in silico techniques, this work describes the design and preparation of 31 novel structural analogues, with which different pharmacophoric features of
