Synthesis of a quaternary polyprenyl ammonium salt

, 2007
Reaction of primary C55-allylic alcohol moraprenol (WT3C7-9-OH, a polyprenol from mulberry leaves) with triethylamine in the presence of phosphorus oxychloride leads to a quaternary ammonium chloride with a good yield (72%) and high cis-stereoselectivity

Ion exchange and ring‐opening reactions of telechelic poly(tetrahydrofuran)s containing terminal cyclic quaternary ammonium salts

, 1987
Anion exchange and ring-opening reactions of cyclic quaternary ammonium salt end groups of poly(tetrahydrofuran) [poly(THF)] were studied. The counter anion exchange reaction of the quaternary ammonium triflate to the sulfonate or to the carboxylate, was
