ALPHA-HYDROXY-GAMMA-BUTYROLACTONE Usage And Synthesis

Chemical Properties

clear colorless to yellow viscous liquid

Uses

α-Hydroxy-γ-butyrolactone may be employed as starting reagent in the synthesis of series of seco-pseudonucleoside synthons via aminolysis. It may be employed as starting reagent in the synthesis of enantiomerically pure orthogonally protected δ-azaproline, via Mitsunobu reaction.

General Description

α-Hydroxy-γ-butyrolactone is a 5-membered cyclic ester. It was obtained via tin-conversion of biomass-derived 1,3-dihydroxyacetone (DHA) and formaldehyde.

Purification Methods

It has been purified by repeated fractionation and forms a colourless liquid. It has to be distilled at high vacuum; otherwise it will dehydrate. The acetox
