Abstract

The resolving ability of a new acidic resolving agent, the hydrogen phthalate of 1, 2: 3, 4-di- O-isopropylidene-α-d-galactopyranose, against various 1-arylalkylamines is described. Treatment of with amines obtain diastereomeric salts·(S) in 2-propanol allowing the corresponding (S)-amines be recovered in good yield and 61–89% ee. Recrystallization in dichloromethane/hexane, and regeneration gave the amines in enhanced enantiomeric ...
