Beckmann Rearrangement of Levulinic Acid: A New Route to the Synthesis of Aspartic Acid
Joshi, U. R.,Limaye, P. A.
, p. 1122 (2007/10/02)
Aspartic acid has been synthesised by a new route.Levulinic acid ester is brominated and the oxime of resultant 3-bromolevulinic ester is aminated, subjected to Beckmann transformation and the product hydrolysed to give aspartic acid in good yield.
