General description

2,4-Dimethoxybenzylamine can be preprepared by reduction (NaBH4 , BF3.OEt2, THF) of 2,4-dimethoxybenzonitrile.

Application

2,4-Dimethoxybenzylamine is an amine nucleophile used to investigate the 1,4- reactivity of 5-bromo-2-indene-1-one. It may be used in the following studies:
  • As an ammonia equivalent in the concise synthesis of a series of 2,4,5-trisubstituted oxazoles, via a tandem Ugi/Robinson-Gabriel reaction sequence.
  • Total synthesis of (-)-muraymycin (MRY) D2 and its epimer, the antibacterial nucleoside natural product.
  • Two-step synthesis of amide derivatives of uracil polyoxin C (UPOC) methyl ester using the Ugi reaction.
  • Synthesis of N-hydroxythiourea.
  • Synthesis of anti-HIV-1 agents.

We describe parallel/combinatorial, solid-phase, supported synthesis of diverse hydroxamates using a common intermediate, an N-derivatized, O-linked hydroxylamine. The method allows the concurrent synthesis of both N-alkyl and N-H hydroxamates and is compatible with a wide range of chemical transformations. The

A simple, two-step synthesis of amide derivatives of uracil polyoxin C (UPOC) methyl ester using the Ugi reaction is described. The four components employed in the Ugi reaction are 2',3'-isopropylidine-protected uridine-5'-aldehyde, 2,4-dimethoxybenzylamine, an isoxazolecarboxylic acid, and the convertible isonitrile N-(2-{[(tert-butyldimethylsilyl)oxy]methyl}phenyl)carbonitrile.
