Bismuth nitrate pentahydrate-induced novel nitration of eugenol
BACKGROUND Eugenol, the main constituent of clove oil possesses a number of medicinal activities. To enhance the medicinal property, structural modification is required. On the other hand, bismuth nitrate pentahydrate has been established as an excellent eco-friendly nitrating agent for several classes of organic compounds. RESULTS Bismuth nitrate pentahydrate-induced nitration of eugenol has...
متن کاملCerium(IV) as Ceric Triethylammonium Nitrate: An Efficient Catalyst for Protection and Deprotection of Alcohols with Dihydropyran
Catalytic amount of Ce(IV) as ceric triethylammonium nitrate (CTEAN) in dichloromethane or acetone can bring about an efficient tetrahydropyranylation of different types of alcohols to afford the corrsesponding tetrahydropyranyl ethers in high yields. Deportection of tetrahydropyranyl ethers can also be achieved efficiently in the presence of this catalyst in methanol.
متن کاملDeprotection of Sulfonyl Aziridines
The deprotection of the chiral N-sulfonyl aziridines 1-3 has been studied under different desulfonylation conditions. Two methods for the efficient deprotection of 2-benzyl-, 2-phenyl-, and 2-carboxyl-N-sulfonylaziridines were found. The desulfonylation with lithium and a catalytic amount of di-tert-butyl biphenyl in THF at -78 °C led to the corresponding NH aziridines with yields up to 85%. Al...
متن کاملActivation and deprotection of F-BODIPYs using boron trihalides.
The activation of F-BODIPYs with boron trihalides, followed by treatment with a nucleophile, effects facile substitution at boron; using water as the nucleophile promotes deprotective removal of the -BF2 moiety and thereby production of the corresponding parent dipyrrin salt in quantitative yield under extremely mild conditions.
متن کاملDeprotection of methylphosphonate oligonucleotides using a novel one-pot procedure.
Deprotection of methylphosphonate oligonucleotides with ethylenediamine was evaluated in a model system. Methylphosphonate sequences of the form 5'-TTTNNTTT, where N was either N4-bz-dC, N4-ibu-dC, N2-ibu-O6-DPC-dG, N2-ibu-dG, N6-bz-dA, or T, were used to determine the extent of modifications that occur during deprotection. Up to 15% of N4-bz-dC was found to transaminate at the C4 position when...
