Use of Bromine and Bromo-Organic Compounds in Organic Synthesis
TL;DR: The use of bromine and different bromo-organic compounds in organic synthesis is outlined and the scope of these reagents for various organic transformations such as bromination, cohalogenation, oxidation, cyclization, ring-opening reactions, substitution, rearrangement, hydrolysis, catalysis, etc is described briefly.

Total synthesis of atroviridin
TL;DR: In this paper, a total synthesis of atroviridin (1 ) based on biosynthetic principles is presented. But the synthesis of the natural product was constructed by coupling aryl bromide 8 with aldehyde 7 and subsequent intramolecular conjugate addition on a quinone precursor.
