First representatives of a new family of isoquinolines, so called boroisoquinolines, were synthesized and characterized. The synthesis was based on the insertion of the difluoroboranyl group into the 1-methylidene-3,4-dihydroisoquinoline core. The optimization of the 2-difluoroboranyl-3,4-dihydroisoquinoline-1(2)-ylidene core led to efficient fluorescence in a range of 400-600 nm with outstanding (>100 nm) Stokes shifts. The compounds might be suitable for reversible or irreversible labelling of proteins, particularly the cannabinoid receptor CB.
首个新的异喹啉家族（即所谓的硼代异喹啉）的代表物得以合成与表征。该合成基于将二氟硼烷基团插入1-亚甲基-3,4-二氢异喹啉核心结构中。对2-二氟硼烷基-3,4-二氢异喹啉-1(2)-亚基核心结构的优化，使其在400 - 600 nm范围内产生高效荧光，并具有出色的（>100 nm）斯托克斯位移。这些化合物可能适用于蛋白质的可逆或不可逆标记，尤其是大麻素受体CB。
