Nitrogen-bonded substituents nucleophilic reactions

Most of the reactions and properties of 1-substituted imidazoles have been discussed earlier in this review. Apart from the utilization of the readily removable benzyl substituent in synthetic procedures leading to 2-substituted imidazoles, perhaps the mostexciting advances have stemmed from the reactions of the 1 -acylimidazoles (imidazolides) which are extremely reactive in such nucleophilic reactions as hydrolysis and alcoholysis.12 The use of such compounds as N,N -carbonyl-diimidazole in peptide synthesis is now commonplace. The silicon-nitrogen bond in N-trimethylsilylimidazoles is also extremely reactive, so reactive that it is attacked by a-halogenocarboxylic esters.361... [Pg.183]
