2-CHLORO-1,3,2-BENZODIOXABOROLE Usage And Synthesis

Uses

B-Chlorocatecholborane can be used:

• To prepare 2-arachidonoylglycerol by acetal cleavage of cis-arachidonoylbenzylidene glycerol.
• To prepare metal boryl complexes (Rh and Ir complexes) through oxidative addition.
• To remove the trityl group in one of the key steps for the synthesis of (?)-dictyostatin.

General Description

B-Chlorocatecholborane is a boron reagent and a Lewis acid, known to facilitate the borylative cyclization of alkynes to yield the borylated heterocycles. It is also used in the preparation of lactones, and thiophenes.
