## Abstract We have developed a stereoselective route to isotopically labeled L‐aspartic acid using L‐serine as a chiral precursor. Labeled serine, prepared biosynthetically was N‐protected by conversion to the N‐__t__‐Boc derivative. (N‐__t__‐Boc)‐[3−^13^C]Serine is cyclized to its β‐lactone which
