Abstract
Convenient processes are described for the synthesis of L-Se-methyselenocysteine from chloroalanine derivatives. The process is easily extendable to other selenium substituted amino acids. DL-Se-methyselenocysteine is easily obtained by a benzaldehyde-catalyzed racemization of L-Se-methyselenocysteine.
