A simple and rapid catalytic dehalogenation process has been used for the preparation of phenylacetic acid -4-3H. Ethyl p-bromophenylacetate was hydrogenated in absolute ethanol solution in the presence of palladium on charcoal catalyst and triethylamine. The ethyl phenylacetate formed was hydrolyze

✦ Synopsis
L-djenkolic acid (a cystine analogue with an -27-CH2-S-linkage) was tritiated by the Wilzbach technique. Tritiation was accompanied by considerable degradation as revealed by discoloration and multiple chromatographic spots. Using a modification of a literature method

## Abstract We have synthesized β‐aminoisobutyric acid (3‐amino‐2‐[^3^H]methyl‐propanoic acid) and β‐ureidoisobutyric acid (3‐[(aminocarbonyl)amino]‐2‐[^3^H]methyl‐propanoic acid) starting with [^3^]thymidine (1‐(2‐deoxy‐β‐D‐ribo‐furanosyl)‐5‐[^3^H]methyluracil). We have developed a simplified enzy
High-specific-activity D-[3-3H]pantothenic acid (5 Ci/mmol) was prepared from commercially available beta-[3-3H]alanine employing Escherichia coli strain DV1 (panD2 pan F1). This strain is defective in beta-alanine synthesis and pantothenate uptake, and under appropriate growth conditions converted
