The synthesis of three potential boron neutron capture therapy agents (68) is reported. The compounds synthesized are comprised of ortho-carborane covalently attached to L-fucose via C-6. Incorporation of the carborane moiety was achieved either through the reaction of an L-fucose-derived alkyne with decaborane or by the coupling of a 6-amino-L-galactopyranose derivative with carborane carboxylic acid chloride (18).Key words: L-fucose, fucosyltransferase, boron neutron capture therapy, ortho-carborane.
报道了三种潜在的硼中子俘获治疗剂(6-8)的合成。合成的化合物由通过C-6与L-岩藻糖共价连接的邻-碳硼烷组成。碳硼烷基团的引入可以通过L-岩藻糖衍生的炔烃与十硼烷的反应或者通过6-氨基-L-半乳糖苷衍生物与硼烷羧酸氯化物(18)的偶联来实现。关键词:L-岩藻糖,岩藻糖转移酶,硼中子俘获治疗,邻-碳硼烷。
