  • Synthesis of new mono-N-tosylated diamine ligands based on (R)-(+)-limonene and their application in asymmetric transfer hydrogenation of ketones and imines
    作者:Piotr Roszkowski、Jan K. Maurin、Zbigniew Czarnocki
    DOI:10.1016/j.tetasy.2013.04.010
    日期:2013.6
    preparation of a new family of enantiopure mono-N-tosylated-1,2-diamines derived from (R)-(+)-limonene is described. (+)-Limonene was transformed into the appropriate N-tosyl derivative using N-tosylaziridination based on chloramine-T trihydrate. Subsequent ring opening by sodium azide afforded the corresponding isomeric azides. Finally, reduction of the azide function gave enantiomerically pure mono-N-tosylated-1
    描述了一种合成方法,该方法可制备新的对映体纯的,衍生自(R)-(+)-柠檬烯的单-N-甲苯磺酰基-1,2-二胺。使用基于氯胺-T三水合物的N-甲苯磺酰基叠氮化将(+)-柠檬烯转化为合适的N-甲苯磺酰基衍生物。随后通过叠氮化钠开环得到相应的异构叠氮化物。最后,叠氮化物功能的降低得到对映体纯的单-N-甲苯磺酸化的1,2-二胺。事实证明,所获得的配体在芳族酮和亚胺的不对称转移氢化方案中是有效的。
  • Synthesis of substituted tetrahydroisoquinolines by lithiation then electrophilic quench
    作者:Ruaa A. Talk、Alexia Duperray、Xiabing Li、Iain Coldham
    DOI:10.1039/c6ob00577b
    日期:——
    Substituted N-tert-butoxycarbonyl (Boc)-1,2,3,4-tetrahydroisoquinolines were prepared and treated with n-butyllithium in THF at −50 °C to test the scope of the metallation and electrophilic quench. The lithiation was optimised by using in situ ReactIR spectroscopy and the rate of rotation of the carbamate was determined. The 1-lithiated intermediates could be trapped with a variety of electrophiles
    制备了取代的N-叔丁氧基羰基(Boc)-1,2,3,4-四氢异喹啉,并在-50°C下用正丁基锂在THF中处理,以测试金属化和亲电淬灭的范围。通过使用原位ReactIR光谱对锂化进行了优化,并确定了氨基甲酸酯的旋转速率。1-锂化的中间体可以被各种亲电试剂捕获,以产生良好产率的1-取代的四氢异喹啉产物。用酸处理或用LiAlH 4还原可转化为N -H或N -Me化合物。该化学方法被用于有效合成生物碱(±)-crispine A和(±)-dysoxyline。
  • A Highly Enantioselective Access to Tetrahydroisoquinoline and β-Carboline Alkaloids with Simple Noyori-Type Catalysts in Aqueous Media
    作者:Laurent Evanno、Joel Ormala、Petri M. Pihko
    DOI:10.1002/chem.200902289
    日期:2009.12.7
    enhancement: A very convenient modified protocol for the enantioselective transfer hydrogenation of dihydroisoquinoline skeletons under aqueous conditions is reported. Unmodified Noyori ligands can be used and the activity of the catalyst is greatly enhanced with silver additives (see scheme). The protocol was used in a very short synthesis of the alkaloids (S)‐harmicine and (S)‐crispine.

    Photosolvolysis of a mixture of cis - and trans-9,10-dimethoxy-5-methyl- 1,3,4,6,7,11b-hexahydro-2H-benzo[a] quinolizinium iodide (2) in methanol gave, after workup, a very low yield of 8,10,11-trimethoxy-3-methyl- 1,2,3,4,5,6,7,8-octahydro-3-benzazecine (3a). Similarly 1,10,11 trimethoxy-6-methyl-3,4,5,6,7,8-hexahydro-1H-2,6-benzoxazecine (8a) and 1,10,11-trimethoxy-6-methyl-1,4,5,6,7,8-hexahydro-2H-3,6-benzoxazecine (16a) were obtained in fair and low yields respectively from the N- methyl tetrahydro-2H,6H-[1,3] oxazino [2,3-a] isoquinolinium (7a) and hexahydro [1,4] oxazino [3,4-a] isoquinolinium (15) iodide precursors; a 1- methyl derivative (8b) of (8a) was also prepared. The ring-opened products 3-[N-2-(4,5-dimethoxy-2-dimethoxymethyl)-phenyl}ethyl-N-methyl]aminopropan-1-ol (9a) and 3-[N-2-(4,5-dimethoxy-2-1′,1′- dimethoxyethyl )-phenyl}ethyl-N-methyl]aminopropan-1-ol (9b) were also obtained from the [1,3] oxazino [2,3-a]- isoquinolinium salt derivatives. Photolysis of (2) and 9,10-dimethoxy-5-methyl-1,3,4,6,7,11b-hexa-hydro[1,4] oxazino [3,4-a] isoquinolinium iodide (15) in acidified aqueous solution afforded, after workup, the benzazecin-8-ol (3b) and hexahydro-2H-3,6-benzoxazecin-1-ol (16b) products respectively, but again in very low yield. Some mechanistic rationalizations of these results are given.Photosolvolysis of 7a-(3,4-dimethoxy)phenyl-4-methyl-2,3,5,6,7,7a- hexahydropyrrolo [2,1-b] oxa-zolium iodide (22) in methanol afforded a high yield of 8-methoxy-4-methyl-8-(3,4-dimethoxy)-phenyl-3,4,5,6,7,8- hexahydro-2H-1,4-oxazocine (24) in a new ring-destruction approach to this ring system. From 13C n.m.r . data, the twist-boat-chair conformation was tentatively assigned to (24) in (D)chloroform solution.
