An efficient, 4-step, one-pot, highly stereoselective route to γ-amino alcohols has been developed via an in situ α,β-unsaturated imine formation, β-boration, reduction (CN) and oxidation (CâB) sequence and especially for certain water-soluble γ-amino alcohols, a further step can be added to directly access the corresponding 1,3-oxazine derivatives.
开发了一种高效的四步一锅法高度立体选择性合成γ-氨基醇的路线,通过原位形成α,β-不饱和亚胺、β-硼化、还原(CN)和氧化(C-B)的顺序,特别是对于某些水溶性γ-氨基醇,还可以增加一步直接获得相应的1,3-噁嗪衍生物。
