(3RS)-[2,3-3H2(N)]-β-Leucine, a substrate for assay of leucine 2,3-amino-mutase, has been synthesized. Ethyl (Z)-3-acetamido-4-methylpent-2-enoate was reduced with 3H2 gas over Pd(C) to (3RS)-[2,3-3H2(N)]-β-leucine ethyl ester, which was hydrolyzed

For studies on the coenzyme B12-dependent enzyme, leucine-2,3-aminomutase, (3R)- and (3S)-beta-leucines were synthesized. The 10-camphorsulfonamide p-nitrobenzyl esters could be resolved by normal-phase HPLC. A much better separation was obtained by

epsilon-Rhodomycinone was converted into 8,9-dehydro-zeta-rhodomycinone, which gave a cis diol with osmium tetroxide and a pair of epimeric epoxides with m-chloroperbenzoic acid. Acid-catalyzed opening of the epoxides gave the corresponding trans dio

New mitomycin C and porfiromycin analogues were prepared by treating mitomycin A and N-methylmitomycin A with a variety of amines, including aziridines, allylamines, propargylamines, chloroalkylamines, hydroxyalkylamines, glycine derivatives, aralkyl
