  N.C.A.18F-labelled norephedrine derivatives via α-aminopropiophenones

  摘要：

  N-protected 2-anlino-1-([F-18]fluorophenyl)-1-propanones are interesting fluorine-18 labelled intermediates to synthesize potential PET-tracers for mapping the adrenergic nervous system of the heart. Several N-protected alpha -aminoalkylarylketones were prepared to examine the direct nucleophilic n.c.a. F-18-fluorination of these carbonyl activated precursors. The influence of different protecting groups, the kind of leaving group and the stereoselective reduction of the keto function have been investigated in order to optimize the radiotracer production. It was shown that the F-18-substitution of the para-trimethylammonium group, e.g. of N-dibenzylated propiophenone, leads to radiochemical yields of up to 60%. The stereoselective reduction of the carbonyl function with formation of the n.c.a. erythro 2-N,N-dibenzylamino-1-(4-[F-18]fluorophenyl)-1-propanol was performed using BH3. THF. The diastereomeric excess was about 80%. Hydrogenolytical debenzylation was achieved with ammonium formiate in presence of palladium on charcoal to give the 4-[F-18]fluoronorephedrine with a radiochemical yield of 15-20% within a total time of 60 min.

  The strategy of stereodivergent reactions on racemic mixtures (stereodivergent RRM) was employed for the first time in intramolecular benzoin reactions and led to the rapid access of chromanones/flavanones with two consecutive stereocenters. The easily separable stereoisomers of the products were obtained with moderate to excellent enantioselectivities in a single step. Catechol type additives proved

  α-Chiral alkyl primary amines are virtually universal synthetic precursors for all other α-chiral N-containing compounds ubiquitous in biological, pharmaceutical, and material sciences. The enantioselective amination of common alkyl halides with ammonia is appealing for potential rapid access to α-chiral primary amines, but has hitherto remained rare due to the multifaceted difficulties in using ammonia

  α-手性烷基伯胺实际上是生物、制药和材料科学中普遍存在的所有其他α-手性含氮化合物的通用合成前体。普通烷基卤与氨的对映选择性胺化对于快速获得 α-手性伯胺很有吸引力，但由于使用氨的多方面困难和不发达的 C(sp 3 )-N 偶联，迄今为止仍然很少见。在这里，我们展示了亚砜亚胺作为优异的氨替代物，用于在温和的热条件下通过铜催化与不同的外消旋仲烷基卤化物（> 60 个例子）对映聚合自由基 C-N 偶联。该反应有效地提供了高度对映体富集的N-烷基亚砜亚胺（产率高达 99% 和 >99% ee），具有仲苄基、炔丙基、α-羰基烷基和 α-氰基烷基立体中心。此外，我们已将由此获得的掩蔽 α-手性伯胺转化为各种合成结构单元、配体和具有 α-手性 N-官能团的药物，如氨基甲酸酯、羧酰胺、仲和叔胺和恶唑啉，常见的α-取代模式。这些结果揭示了对映会聚自由基交叉偶联作为一般手性碳-杂原子形成策略的潜力。
