Abstract External imaging of the pancreas is made possible by taking advantage of that organ's large requirement for exogenous aminoacids. The only successful approach thus far has been the substitution of selenium for the sulfur atom in aminoacids naturally containing sulfur, specifically selenomethionine labeled with selenium‐75. The synthesis of a class of selenium‐containing aminoacids has been undertaken

Synthesis of selenocystine derivatives from cystine by applying the transformation reaction from disulfides to diselenides
A stepwise conversion of a disulfide (SS) to a diselenide (SeSe) bond through the corresponding iodide intermediate was implemented and was applied to the synthesis of selenocystamine and l-selenocystine derivatives from cystamine and l-cystine, respectively, in moderate yields.
