Method for preparing carboxylic acid by one-pot method
-
Paragraph 0041-0045, (2021/01/29)
The invention discloses a method for preparing carboxylic acid by a one-pot method, which comprises the steps of carrying out a Corey-Fuchs process on 1,1-dibromo olefin under the action of n-butyllithium, reacting with isopropanol pinacol borate, quenching with hydrogen chloride, oxidizing with an oxidant, separating and purifying to obtain carboxylic acid. The method disclosed by the invention is a one-pot preparation method, is simple and convenient to operate, does not need to use metal catalysis, uses cheap and easily available reagents for reaction, is green and environment-friendly, hasmild reaction conditions and wide substrate applicability, and provides a new way for rapidly preparing a series of carboxylic acids containing different functional groups.

A new fluorescent photoremovable protecting group (FPRPG) based on acetylcarbazole framework has been explored for the first time release of single and dual (similar or different) substrates from single chromophore. Mechanistic studies of the photorelease process revealed that photorelease of two (similar or different) substrates from acetyl carbazole proceeds via a stepwise pathway. Further, we constructed photoresponsive dual drug delivery system (DDS) to release two different anticancer drugs (caffeic acid and chlorambucil, 1 equiv each). In vitro study reveals that our DDS exhibit excellent properties like biocompatibility, cellular uptake, and photoregulated dual drug release.
