Highly efficient preparation of amides from aminium carboxylates using N-(p-toluenesulfonyl) imidazole
Behrouz, Somayeh,Rad, Mohammad Navid Soltani,Forouhari, Elham
, p. 101 - 106 (2016/03/08)
Treatment of aminium carboxylates with N-(p-toluenesulfonyl)imidazole in the presence of triethylamine in DMF at 100 °C afforded the corresponding amides in good to excellent yields. N-(p-Toluenesulfonyl)imidazole proved to be a highly efficient coupling reagent for the preparation of numerous structurally diverse primary, secondary and tertiary amides.
Solvent free, highly chemoselective N and O-acylation on silica and silica magnesium oxide: A recyclable solid surface
Ghosh, Pranab,Mandal, Amitava
, p. 261 - 268 (2012/10/29)
Silica or silica/magnesium oxide mixed surface mediates the N and O-acylation, benzoylation or sulfonylation of hosts of substrates under solvent free conditions at ambient temperature with high chemoselectivity.
A CONVENIENT SYNTHESIS OF PHOSPHORUS AND SULFONYL-SUBSTITUTED N-IMIDAZOLES (TRIAZOLES) USING THE CORRESPONDING ACID CHLORIDES AND N-TRIMETHYLSILYL IMIDAZOLES (TRIAZOLES)
Dabkowski, W.,Michalski, J.,Skrzypczynski, Z.
, p. 321 - 326 (2007/10/02)
The synthetic route phosphorus and sulfonyl-substituted N-imidazoles (triazoles) has been elaborated based on the method proposed by Birkofer et al.The appropriate compounds are obtained in high yield and of analytical purity by the action of N-trimethylsilyl imidazole (triazole) on the corresponding acid chlorides.
