A procedure for the mild conversion of a carbonitrile to the corresponding carboxylic acid by first using trifluoroacetic acid in the presence of a catalytic amount of mercuric ion followed by oxidative hydrolysis with dinitrogen tetroxide is described herein. The use of this procedure in the preparation of 1,3,4,5-tetra-O-benzoyl-2,6-dideoxy-2,6-imino-D-glycero-L-gulo-heptitol hydrochloride is also described here.
本文描述了一种将碳腈温和地转化为相应羧酸的方法,首先使用三氟乙酸,在汞离子的催化下进行,然后进行氧化水解,使用双氮四氧化物。同时还描述了在制备1,3,4,5-四-O-苯甲酰-2,6-二去氧-2,6-亚氨基-D-甘露-L-戊糖酸盐的过程中使用该方法。
