(-)-O-ACETYL-L-MALIC ANHYDRIDE Usage And Synthesis

Chemical Properties	White Crystalline Solid
Uses	(-)-O-Acetyl-L-Malic Anhydride can be used as intermediates for detergents via O-acetylmalic acid amides. Regioselective ring opening of malic acid anhydrides by carbon nucleophiles
Uses	(S)-(-)-2-Acetoxysuccinic anhydride is used as intermediates for detergents via O-acetylmalic acid amides. Regioselective ring opening of malic acid anhydrides by carbon nucleophiles.
Purification Methods	Recrystallise it from Ac2O and dry it in a vacuum over KOH, or by washing it with dry Et2O due to its deliquescent nature. [Jones J Chem Soc 788 1933, Henrot et al. Synth Commun 16 183 1986, Shiuey et al. J Org Chem 52 1040 1988, RS: Cohen et al. J Am Chem Soc 88 5306 1966.]
