## Abstract Literature preparations of 2‐amino‐6‐nitrobenzoic acid are usually based on phthalic anhydride. In order to make [benzene‐^14^C(U)]‐2‐amino‐6‐nitrobenzoic acid, [benzene‐^14^C(U)]‐phthalic anhydride has to be prepared in multiple steps from [^14^C(U)]‐benzene, resulting in an unacceptab
Several synthetic /J,f-unsaturated &amino acids have recently been developed as specific irreversible inhibitors of pyridoxal l,hosl,hate dependent enzymes. 1 A few naturally occurring P,d-unsaturated amino acids are known to function as specific enzyme inhibitors 2. including rhizobitoxine inhibiti
Methyl 8-oxooctanoate-4,5-d and methyl 12-oxododecanoate-4,5,8,9-d4 were prepared for use as inzermediates in the synthesis of a series of labelled fatty acid methyl esters. Synthesis of the two compounds began with monoozonization and sodium acetate cleavage of 1,4-cyclooctadiene and 1,5,9-~yclodod
