Beschreibung

Allgemeine Beschreibung

(S)-(+)-1,2-Isopropylideneglycerol is a key building block for the synthesis of glycerides and of phosphoglycerides.

Anwendung

(S)-(+)-1,2-Isopropylideneglycerol may be used as a calibration standard during the GC analysis of the solketal yield and glycerol conversion in the ketalization reaction of glycerol and acetone. It may also be used to synthesize 1,2-dipalmitoyl-3-benzyl-sn-glycerol and 1-O-(Z)-octadecenyl-sn-glycerol, an intermediate for plasmalogen synthesis.

Used in a synthesis of a chiral allylic triol via extrusion of SO₂ from an α,β-epoxysulfone.
