Organoboranes react with nitrogen-13 labeled ammonia to produce alkylamines in moderate yield. When 13N labeled ammonia was bubbled into a tetrahydrofuran solution containing 0.5M tridecylborane, 1-[13N]aminodecane was formed in 25-30 min from the end of bombardment (EOB) in 40-60% overall yield. 1-

L-[13N]Tyrosine and L-[13N]phenylalanine were synthesized using immobilized enzymes by two methods. In method 1, [13N]ammonia is converted to L-[13N]glutamate; transamination with p-hydroxyphenylpyruvate yields L-[13N]tyrosine. [13N]Tyrosine is separated from other labeled intermediates on a Poropak
The adduct __O__^6^‐carboxymethyl‐2′‐deoxyguanosine (O^6^CMdG) is of importance as it has been previously linked to high red meat diet in humans, and as yet, a liquid chromatography‐mass spectrometry (LC‐MS) method has not been developed due to lack of appropriate standards. The synthesis of the deu
