In an article, author is Jaiswal, Anjali, once mentioned the application of 321-14-2, Name: 5-Chloro-2-hydroxybenzoic acid, Name is 5-Chloro-2-hydroxybenzoic acid, molecular formula is C7H5ClO3, molecular weight is 172.57, MDL number is MFCD00002457, category is indole-building-block. Now introduce a scientific discovery about this category.
An efficient regioselective C-3 acylation of free indoles (N-H) has been accomplished via oxidative decarbethoxylation of easily available ethyl arylacetates using Cu(OAc)(2) and KOtBu in DMSO.
If you are interested in 321-14-2, you can contact me at any time and look forward to more communication. Name: 5-Chloro-2-hydroxybenzoic acid.
