A protocol for amide bond formation with electron deficient amines and sterically hindered substrates.
A protocol for amide coupling by in situ formation of acyl fluorides and reaction with amines at elevated temperature has been developed and found to be efficient for coupling of sterically hindered substrates and electron deficient amines where standard methods failed.
متن کاملTriphenylphosphine-catalysed amide bond formation between carboxylic acids and amines.
Unactivated carboxylic acids and amines undergo organocatalytic Ph3P/CCl4-mediated amide bond formation by employing in situ reduction of triphenylphosphine oxide to triphenylphosphine in the presence of diethoxymethylsilane and bis(4-nitrophenyl)phosphate.
متن کاملAmide synthesis by nucleophilic attack of vinyl azides.
A method for the synthesis of amide-containing molecules was developed using vinyl azides as an enamine-type nucleophile towards carbon electrophiles, such as imines, aldehydes, and carbocations that were generated from alcohols in the presence of BF3 ⋅OEt2 . After nucleophilic attack of the vinyl azide, a substituent of the resulting iminodiazonium ion intermediate migrates to form a nitrilium...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
