Safety of ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)In 2015 ,《An expedient synthesis of oxazepino and oxazocino quinazolines》 appeared in Tetrahedron Letters. The author of the article were Hensbergen, Albertus Wijnand; Mills, Vanessa R.; Collins, Ian; Jones, Alan M.. The article conveys some information:
A synthetic route to a new class of privileged tri- and tetra-cyclic quinazolines containing a medium-sized ring, e.g. I, is reported. An expedient synthetic route involving nucleophilic aromatic substitution, and sequential Niementowski and BOP-mediated ring closures afforded a collection of analogs. The scope of the reaction was explored in terms of cyclic and acyclic linkers, ring size and substitution pattern. In the part of experimental materials, we found many familiar compounds, such as ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6Safety of ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V))
((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6) is used as a reagent for peptide coupling, lactonization, selective esterification, amidation of alfa amino acids without racemization and synthesis of magnolamide for antioxidative activity and catalyst for 9-acridinecaroboxamide derivative. It is also used as a precursor for the synthesis of phenyl esters of amino acids.Safety of ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)
