Application

3,4-(Methylenedioxy)toluene can be used as a cation scavenger for the selective cleavage of 4-(3,4-dimethoxyphenyl)benzyl (DMPBn) ethers affording the corresponding deprotected products in the presence of trifluoroacetic acid (TFA) in anhydrous CH2Cl2.[1]
It can also be used as a starting material to prepare:
  • 1,3-Benzodioxole-5-carboxaldehyde via photooxidation using CBr4.[2]
  • 6-Methyl-1,3-benzodioxole-5-carboxaldehyde by treating with dichloromethylmethyl ether and TiCl4.[3]

A reliable reagent system for the cleavage of 4-(3,4-dimethoxyphenyl)benzyl (DMPBn) ethers under acidic conditions has been established. Treatment of DMPBn-protected mono- and pseudodisaccharides with TFA in anhydrous CH2Cl2 and 3,4-(methylenedioxy)toluene as a cation scavenger resulted in the selective cleavage of
