Total synthesis of antibacterial dibromotyrosine derived alkaloid purpuramine-K#

The first total synthesis of a dibromotyrosine derived alkaloid purpuramine K 1 reported for possible anti-bacterial activity against gram-positive bacteria viz: Staphylococcus aureus, Bacillus subtilis, Bacillus sphaericus and gram-negative bacteria like Chromobacterium violaceum, Klebsiella aerogenes, and Pseudomonas aeruginosa has been achieved. The synthesis involves preparation of methyl-3-bromopropyl carbamate 6, and Boc protected 2-[3,5-dibromo, 4-hydroxy phenyl] ethyl amine 13 which is followed by coupling of these two structural fragments to give corresponding ether 14. After deprotection of Boc group in compound 14, it is reacted with 4-hydroxyphenyl pyruvic acid oxime derivative 17 using EDCI/HOBT to give compound 18, which is further transformed to purpuramine K.
