General description

4,5-Dimethoxy-2-nitrobenzyl bromide (DMNBB, 1-(Bromomethyl)-4,5-dimethoxy-2-nitrobenzene) is a 4,5-dimethoxy-2-nitrobenzyl derivative. 4,5-Dimethoxy-2-nitrobenzyl (DMNB) group of DMNBB is used as a photolabile protecting group in caging technology to develop pro-drugs. Synthesis of 1-(bromomethyl)-4,5-dimethoxy-2-nitrobenzene by using 6-nitroveratraldehyde as starting reagent has been reported.

Application

4,5-Dimethoxy-2-nitrobenzyl bromide (DMNB bromide, 6-nitroveratryl bromide) is suitable reagent used in the synthesis of N-(4,5-dimethoxy-2-nitrobenzyl)vanillylamine which forms caged vanilloid. It may be used in the synthesis of the following:
  • 4-(4′,5′-dimethoxy-2-nitrobenzyloxy)benzaldehyde, a DMNB-caged aldehyde
  • N-[4-[(4,5-dimethoxy-2-nitrobenzyl)oxy]-3-methoxybenzyl]acetamide
  • caged derivative of pyridostatin ([C]-PDS)
  • photosensitive polyimide (PI-DMNB)
  • caged β-ecdysone
  • 4-tert-butyldimethylsilyloxy-1-(2-deoxy-3,5-di-O-toluoyl-β-D-ribofuranosyl)-2-(6-nitroveratrylthio)-1H-benzimidazole, an intermediate in synthesis of phosphoramidite bearing 4-hydroxy-2-mercaptobenzimidazole (SBNV) nucleobase
  • alkylation of dihydrofluorescein
  • 4-(4′,5′-Dimethoxy-2′-nitrobenzyloxy)benzaldehyde
