3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Reference of 108940-96-1

Concise total synthesis of aplysinellamides A and B was written by Gan, Haifeng;Huang, Yu;Feng, Weiyang;Zhu, Wentong;Guo, Kai. And the article was included in Journal of Chemical Research in 2015.Reference of 108940-96-1 This article mentions the following:

Concise and efficient total syntheses of bromotyrosine-derived metabolites aplysinellamides A (I·TFA) and B (II·TFA), isolated from Australian marine sponge Aplysinella sp., have been accomplished in seven steps. A condensation between cinnamic acid and Boc-D-lysine Me ester was applied to form the amide skeleton as a key step. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1Reference of 108940-96-1).
