General description

Hydrogen chloride solution contains 4.0 M hydrogen chloride in 1,4-dioxane as the solvent. It is commonly used as a deprotection reagent during the deprotection of the tert-butoxycarbonyl (Boc) group of various amino acids and peptides. Additionally, it serves as a reagent in various organic synthesis reactions, including the synthesis of N-9-Fluorenylmethoxycarbonyl- (Fmoc) amino-acid chlorides.

Application

Hydrogen chloride solution (4.0 M in dioxane) can be used as:     
  • A reagent for the deprotection of the N-Boc protecting group from various heterocyclic derivatives.     
  • A reagent for the deprotection of polymer protecting groups. For instance, deprotection of benzyl ether-protected polymer.      
  • A polymerization initiator in combination with ZnCl2 in the synthesis of formyl terminated poly(ethyl vinyl ether) from ethyl vinyl ether (EVE).

A series of 2-piperidin-4-yl-benzimidazoles were synthesized and evaluated for antibacterial activities. Certain compounds inhibit bacterial growth with low micromolar minimal inhibitory concentration (MIC). These benzimidazoles are effective against both Gram-positive and Gram-negative bacteria of clinical importance, particularly enterococci, and represent
