combination of an aldehyde, an allylic bromide, and tert-butanesulfinamide in the presence of indium metal and titanium tetraethoxide allows straightforward access to homoallylamine derivatives in high yields and stereoselectivities. Moreover, the synthetic utility of the enantioenriched homoallylamine derived from n-decanal was illustrated in a concise synthesis of (+)-isosolenopsin. In this context, similar
在存在铟金属和四乙氧基钛的情况下,将醛,烯丙基溴和叔丁烷亚磺酰胺的组合可以高产率和立体选择性直接获得均烯丙胺衍生物。此外,在(+)-异异视紫红质的简明合成中说明了衍生自n-癸醛的富含对映体的高烯丙胺的合成效用。在这种情况下,其他团体最近在合成天然生物碱中也使用了类似的高烯丙胺。
