Abstract
Achieving substrate generality in asymmetric catalysis remains a long-standing goal, particularly for the selective construction of chiral heteroatoms. Compared with carbon, sulfur, phosphorus and silicon stereogenic centres, methods for the construction of their boron and germanium congeners remain very scarce. Chiral (hetero) spirocycles are of relevance in several research domains. Methods effective for constructing carbon-centred chiral spirocycles do not translate to boron and germanium, leaving these chiral centres unexplored. We describe a unified strategy for constructing carbon, boron and germanium-centred chiral spirocyclic skeletons via enantioselective hetero [2+2+2] cycloaddition of a bis-alkyne with a nitrile. A chiral designer Ni(0) N-heterocyclic carbene complex enables the required long-range enantioinduction. The resulting enantio-enriched spirocycles feature a pyridine motif, making them exploitable for ligand design and functional materials featuring attractive photophysical and chiroptical properties.
在不对称催化中实现底物的普遍性仍然是一个长期的目标,特别是对于手性杂原子的选择性构建。与碳、硫、磷和硅的立体中心相比,构建它们的硼和锗同系物的方法仍然很少。手性(异)螺环在许多研究领域都具有相关性。构建碳中心手性旋环的有效方法不能转化为硼和锗,使这些手性中心未被探索。我们描述了一种统一的策略,通过对映选择性异[2+2+2]环加成双炔和腈来构建以碳、硼和锗为中心的手性螺旋环骨架。手性设计物Ni(0) n -杂环羰基络合物实现了所需的远程对映体诱导。所得到的富含对映体的螺旋环具有吡啶基序,使其可用于配体设计和具有吸引的光物理和热学性质的功能材料。
