An efficient approach to the enantioselective synthesis of a series of amino acids from either bromoacetyl bromide or glycine is described using a [2,3]‐sigmatropic rearrangement to establish the stereogenic centre at C‐2 under mild conditions. Protected allylglycine5is a valuable building block to several amino acids e.g. hydrolytic cleavage of the auxiliary in5followed by deprotection gaveL‐allylglycine in 92% yield whilst oxidative cleavage of the terminal alkene followed by deprotection gaveL‐aspartic acid in 67% yield over the 2 steps. Furthermore alkene5may be converted to hydroxy ester8which is an intermediate for the synthesis of various amino acids includingL‐lysine andL‐proline. Since the enantiomer of sultam1is commercially available, the analogousD‐amino acids may be synthesised. This chemistry is readily adapted for the incorporation of isotopic labels for example for the synthesis of [1,2‐13C2,15N]‐L‐homoserine14. Copyright © 2007 John Wiley & Sons, Ltd.
