A specific enzymatic method was developed for the determinations of L-omithine and L-A'-pyrroline-S-carboxylate using two coupling enzymes, omithine aminotransferase and A\*-pyrroline-Scarboxylate reductase. Using this method, omithine in rat tissues and human serum could be determined at the nanomo

## Abstract D,Lβ3β[^11^C]βAlanine was prepared by methylation with ^11^CH~3~I of tert butyl 2βisocyanoacetate and subsequent hydrolysis. Enzymatic reaction using glutamate pyruvate transaminase and lactate dehydrogenase in a coupled reaction yields Lβ3β[^11^C]βlactic acid. The radiochemical yield i
Intramolecular Cycloaddition of 5-Alkenyl-1-pyrroline 1-Oxide-5carboxylic Esters. -Thermal treatment of the pyrroline-1-oxides (Ia)-(Ic) results in intramolecular cyclization to give the azatricyclo compounds (II) and (III), while (Id) fails to react. The products are subjected to hydrogenolysis, f
## Abstract A versatile method for ^14^C labeling of 2βmethoxypyrimidineβ5βcarboxylic acid at the 2βposition has been developed after encountering difficulties with traditional approaches to label the carboxyl function. The method developed can also be used for ^14^C labeling other positions of the
