  • Synthesis of Erythrina and Related Alkaloids. XXX. Photochemical Approach. (1). Synthesis of Key Intermediates to Erythrina Alkaloids by Intermolecular (2+2) Photocycloaddition Followed by 1,3-Shift.

    A novel synthetic route to Erythrina alkaloids consisting in [2+2] intermolecular photocycloaddition of the isoquinolinodioxopyrroline 4 to 2-trimethylsilyloxybutadienes and the subsequent ring enlargement reaction of the trimethylsilyloxyvinylcyclobutane 5 by thermal or tetrabutylammonium flouride(TBAF)-induced 1, 3-shift was developed. The TBAF method was particularly useful, offering a good yield under mild reaction conditions. Thus, photoannulation of 4 with 1-methoxy-3-trimethylsilyloxybutadiene, followed by hydride reduction, TBAF-induced 1, 3-shift, and hydrogenation gave the 7α-hydroxy-2, 8-dioxoerythrinan 19 in overall 45% yield, and this product was converted, in 70% yield, into the 1, 7-cycloerythrinan 24, a key intermediate for the total synthesis of Erythrina alkaloids.
    一种合成Erythrina生物碱的新路线是通过[2+2]分子间光循环加成反应,将异喹啉二氧吡咯啉4与2-三甲基硅氧基丁二烯进行反应,随后通过热反应或四丁基氟铵(TBAF)诱导的1,3迁移反应对三甲基硅氧基乙烯基环丁烷5进行环扩展。TBAF方法尤其有效,在温和的反应条件下提供了较好的产率。因此,首先将4与1-甲氧基-3-三甲基硅氧基丁二烯进行光环加成,随后进行氢化还原、TBAF诱导的1,3迁移及加氢反应,最终得到7α-羟基-2,8-二氧Erythrina 19,总体产率为45%,而该产物进一步转化为70%的产率,得到1,7-环Erythrina 24,这是Erythrina生物碱全合成中的一个关键中间体。

  • Chiral Synthesis of Erythrina Alkaloids. (2). Synthesis of enantio-Type Erythrinan Alkaloids Utilizing Asymmetric Acylation and Kinetic Resolution of Diastereomers.

    Oxalylation of the enamino-ester 13 derived from the L-dopa derivative 12 gave the dioxopyrroline of (6S)-configuration (15A) diastereoselectively (50-60% diastereomer excess). This was converted to a mixture of erythrinans of (5S, 6R, 7R, 10S) and (5R, 6S, 7S, 10S) configuration by cyclization with BF3·Et2O. The de of the major diastereomer (A) was elevated to 82% by application of a kinetic resolution of diastereomers (partial hydrolysis of the ethylene acetal group), where the minor diastereomer (B) was hydrolyzed more rapidly. The acetal 17A which remained unchanged was converted, in several steps, to the enantio-type erythrinan alkaloid, (-)-3-demethoxyerythratidinone (-)-7, and also to the 1, 7-cycloerythrinan (-)-9, a key intermediate to Erythrina alkaloids. The more easily hydrolyzable diastereomer (B) was similarly converted to the enantiomer (+)-9. The mechanism of partial racemization, sometimes observed in the product, is discussed.
    由 L-多巴衍生物 12 衍生出的烯酰胺酯 13 通过草酰化反应,非对映选择性地得到了 (6S) 构型的二氧吡咯啉 (15A)(非对映异构体过量率为 50-60%)。通过与 BF3-Et2O 环化,将其转化为(5S, 6R, 7R, 10S)和(5R, 6S, 7S, 10S)构型的赤藓红混合物。通过非对映异构体的动力学解析(乙烯缩醛基团的部分水解),主要非对映异构体(A)的de 提高到 82%,而次要非对映异构体(B)的水解速度更快。保持不变的乙缩醛 17A 经过几个步骤转化为对映体型红花楠生物碱 (-)-3-demethoxyerythratidinone (-)-7,以及红花楠生物碱的关键中间体 1,7-环红花楠 (-)-9。更容易水解的非对映异构体(B)也同样转化为对映体(+)-9。本文讨论了有时在产品中观察到的部分消旋化机制。

    Treatment of 2, 8-dioxo-1, 7-cycloerythrinans with phenylselenenyl chloride in the presence of BF3·Et2O as a catalyst gave 3-chloro-3-phenylselenenyl derivaties through the 3-phenylselenenyl derivative, which changed into the Δ3-3-phenylselenenyl derivative on further reaction.Both the 3-phenylselenenyl and 3-chloro-3-phenylselenenyl derivatives gave the 3, 3-dimethoxy derivative on treatment with mercury (II) perchlorate (MPC) in methanol, thus providing a new method for introduction of a masked carbonyl group at the α-position to the original carbonyl group.Thus, the reaction of 1 with phenylselenenyl chloride under acidic conditions followed by MPC treatment in methanol and borohydride reduction gave the 2α-hydroxy-3, 3-dimethoxy derivative in 57% yield.This was converted to the conjugated ketone in four steps (72%).The carbomethoxy group of this compound was removed by the CaCl2-dimethyl sulfoxide-3-ethylpentane-3-thiol method to give the enone 4(70-80%) which isomerized to the conjugated ketone 25c(100%).This ws converted to a natural Erythrina alkaloid, (±)-erysotramidine (5), in four steps (31%), and thence to (±)-erosotrine (6).
