Aminoalkohole, 3. Mitt. Ein Verfahren zur Herstellung von enantiomerenreinen pharmakologisch aktiven N-substituierten ?-Aminoalkoholen
摘要:
A synthesis of N-substituted beta-aminoalcohols is described starting from enantiomerically pure O-MBF- or O-MBE-protected beta-aminoalcohols which can be prepared via LiAlH4 reduction of O-protected cyanohydrines.
Three kinds of sulfated β‐cyclodextrin (S‐β‐CD), including a single isomer, heptakis‐6‐sulfato‐β‐cyclodextrin (HS‐β‐CD), degree of substitution (DS) of 7, which was synthesized in our laboratory and another two commercialized randomly substituted mixtures, a sulfated β‐cyclodextrin with DS of 7 to 11, as well as a highly sulfated‐β‐cyclodextrin with DS of 12 to 15, were used for the enantioresolution
Characteristic and complementary chiral recognition ability of four recently developed immobilized chiral stationary phases based on amylose and cellulose phenyl carbamates and benzoates
various immobilizedchiralstationaryphases (CSPs) have been developed. The immobilized CSPs have opened up possibilities not only maintaining the high chiral recognition abilities as well as corresponding coated ones but also affording high durability to various mobile phase. This report directed to investigate enantioseparation of recently launched four immobilized CSPs with cellulose and amylose

In this study, a novelhydroxypropyl‐γ‐cyclodextrin (HP‐γ‐CD) functionalized monolithic capillary column was prepared by one‐pot sequential strategy and used for chiralseparation in capillaryelectrochromatography for the first time. In one pot, GMA‐HP‐γ‐CD as functional monomer was allowed to be formed via the ring opening reaction between HP‐γ‐CD and glycidyl methacrylate (GMA) catalyzed by 1,8‐diazabicyclo[5
