Preparation of a New Chiral Stationary Phase Based on (2S,3S)-O,O'-Bis-(10-undecenoyl)-N,N'-bis-(3,5-dinitrobenzoyl)-2,3-diamino-1,4-butandiol and Its Application

Abstract

A new liquid chromatographic chiral stationary phase based on (2S,3S)-O,O'-bis-(10-undecenoyl)-N,N'-bis-(3,5-dinitrobenzoyl)-2,3-diamino-1,4-butandiol was prepared starting from (2R,3R)-1,4-bis(benzyloxy)-2,3-butanediol. The new chiral stationary phase was applied to the resolution of racemic anilide derivatives of N-acetyl-a-amino acids, 1,1'-bi-2-naphthol and 3,3'-diaryl-1,1'-bi-2-naphthols. The CSP was also applied to the resolution of some chiral drugs including a diuretic, bendroflumethiazide, and non-steroidal anti-inflammatory agents such naproxen and alminoprofen. In every case, the chiral recognition efficiency of the new CSP was quite excellent.ࡺ?⨀ЀĀ衺?⨀ЀĀऐ돀졽?⨀堘�⨀ꢐ?⨀돐좐?⨀��⨀킐?⨀뤏덐?⨀렏頏࢑?⨀਀࢑?⨀ᢑ?⨀؀ကᢑ?⨀?幺Ѐက䂑?⨀䂑?⨀
