✦ Synopsis
A convenient method for the synthesis of L-tryptophan analogues is described. The method utilizes E. coli tryptophan synthetase, which catalyses the condensation of indole and L-serine to yield L-tryptophan. It is found :hat several indole analogues will replace indole as substrate for the enzyme to give the corresponding L-tryptophan analogues in good yield. By using ['"Clserine, analogues can be prepared radioactively labeled in the side-chain carbon atoms.

## Abstract A synthetic approach to the synthesis of novel tryptophan derivatives and benzofuran‐containing amino acids is detailed. The sequence starts from enzymatically resolved enantiopure acetylene‐containing amino acids, of which the acetylene function can be efficiently transformed into the
O-acetylserine sulfhydrase in the form of a crude extract from Salmonella typhimurium LT2 was used for the production of L-cysteine from L-O-acetylserine and sodium hydrosulfide at pH 7.0 and 25 degrees C. The two substrates have quite different pH stability relationships. O-Acetylserine readily rea
L-[1.2-13C2, 15N]Serine was prepared from [1,2-13C2, 15N]glycine on a gram scale by the use of the enzyme serine hydroxymethyltransferase. The reaction was monitored by 13C-NMR spectroscopy. This is the first simultaneously 13C- and 15N-labelled serine isotopomer so far reported. Part of the product
