Abstract

Abstract Studies of the stabilities of a series of N-acylimidazoles towards acidic and basic conditions of potential usefulness for the removal of common temporary protection in peptide and oligonucleotide synthesis are presented. N-Acylimidazoles with a variety of substituents in the acyl component were prepared and treated with 3% trifluoroacetic acid (TFA) in chloroform and with 2% 1, 8-diazabicyclo [5.4. 0] undec-7-ene (DBU) in N, N- ...
