Outline of Final Research Achievements

We developed Pd(II)-mediated rapid 11C-cyanation of (hetero)arylborons. This method showed excellent functional group tolerance and allowed for the preparation of various [11C]cyano(hetero)arenes.On the basis of this invention, we futherely developed synthetic methods for a wide range of [11C]5-aryltetrazoles and [11C]2,4-diamino-6-aryl-1,3,5-triazines via rapid cyclization of [cyano-11C]cyano(hetero)arenes with trimethylsilyl azide (TMSN3) or dicyandiamide, respectively.

Academic Significance and Societal Importance of the Research Achievements

官能基許容性に優れた独創的[11C]シアン標識法を開発した。該法で得られた[11C-CN]ニトリルを放射性前駆体として、[11C]tetraozle、[11C]triazineなど代表的なへテロ環の環内炭素の11C標識を実現できた。こられの新規な標識法は、多彩な生体機能性分子や医薬品のPETトレーサー化へ応用にできる。本研究の成果には、基礎的な有機化学と標識化学に知見を与えるのみならず、生命科学研究で有効なPETトレーサーの開発が大きく推進されることで、PETイメージングを用いる病気早期診断と創薬マイクロドース研究、オーダーメイド医療など、幅広い応用研究に貢献できる。
