Descrizione

Descrizione generale

Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.

The chiral stationary phase in γ-DEX 225 columns contains 2,3-di-O-acetyl-6-0-TBDMS-γ-cyclodextrin embedded in an intermediate polarity phase.

Applicazioni

γ-DEX^™ 225 GC column was used during asymmetric highly enantioselective copper catalytic conjugate addition of Et₂Zn to enones, using monodentate chiral spiro phosphoramidite ligands.
