日期:2007.3.16
A one-pot, enantioselective synthesis of N-aryl propargylic amines, using alkynylation reagents obtained from dimethylzinc and terminal acetylenes in combination with various aldehydes and o-methoxyaniline as starting materials, has been developed. Enantiopure beta-amino alcohols derivedfromnorephedrine were used as non-covalent chiral auxiliaries, both in stoichiometric or substoichiometric amount

The asymmetric totalsynthesis of three paspaline-derived indole diterpenes paspalicine, paspalinine and paspalinine-13-ene is reported. This synthesis features a green Achmatowicz rearrangement/bicycloketalization for the efficient construction of FG rings, a cascade ring-closing metathesis of dienyne for highly regioselective formation of CD rings, and four palladium-mediated reactions to forge BE
报道了三种paspaline衍生的吲哚二萜paspalicine、paspalinine和paspalinine-13-ene的不对称全合成。该合成具有用于高效构建 FG 环的绿色 Achmatowicz 重排/双环缩酮化、用于高度区域选择性形成 CD 环的二烯的级联闭环复分解以及用于形成 BE 环的四个钯介导的反应。
