  • Synthesis of Erythrina and related alkaloids. XVI Diels-Alder approach : Total synthesis of dl-erysotrine, dl-erythraline, dl-erysotramidine, dl-8-oxoerythraline and their 3-epimers.

    Total synthesis of erythrinan alkaloids was achieved by a strategy based on the Diels-Alder reaction of activated butadienes to a dioxopyrroline. The reaction of isoquinolinopyrrolinedione (15) with 1, 3-bis-O-substituted butadienes proceeded in a regiospecific and stereoselective manner to give erythrinan derivatives (20) and (21). Lithium borohydride reduction of the adduct (20) or (21), followed by acid hydrolysis afforded the enone (33). Mesylation of 33 and subsequent demethoxycarbonylation of 42 under neutral conditions gave the dienone (43). Meerwein-Ponndorf reduction of 43 and subsequent methylation afforded erysotramidine (2a) and 8-oxoerythraline (2b). Aluminum hydride reduction of the 8-oxo derivatives (2) furnished dl-erysotrine (1a) and dl-erythraline (1b).
    基于激活的丁二烯与二氧吡咯啉进行Diels-Alder反应的策略,实现了erythrinan类生物碱的全合成。异喹啉吡咯二酮(15)与1,3-双氧取代的丁二烯反应,以区域特异性和立体选择性的方式生成erythrinan衍生物(20)和(21)。通过氢化物还原加合物(20)或(21),随后进行酸解得到烯酮(33)。对33进行甲磺酰化,随后在中性条件下进行脱甲氧羰基化得到二烯酮(43)。对43进行Meerwein-Ponndorf还原,随后进行甲基化得到erysotramidine(2a)和8-氧代erythraline(2b)。对8-氧代衍生物(2)进行铝氢化还原得到dl-erysotrine(1a)和dl-erythraline(1b)。

    Four stereoisomers of 1,2-epoxy-3-hydroxyerythrinans are synthesized and their stereochemistries determined unambiguously. Of these, the 1,2α-epoxy-3α-alcohol 4 is converted to the alkenoid-type alkaloid, (±)-erythratidine 1, utilizing reductive migration of an α,β-unsaturated γ,δ-epoxyamide with samarium diiodide as a key step.

    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).
    处理2, 8-二氧代-1, 7-环赤霉烷与苯化物,在BF3·Et2O的催化下,得到3--3-苯烯衍生物,通过3-苯烯衍生物进一步反应转变为Δ3-3-苯烯衍生物。无论是3-苯烯衍生物还是3--3-苯烯衍生物,在与甲醇中的汞(II)高氯酸盐(MPC)处理时,均可得到3, 3-二甲氧基衍生物,从而提供了一种在原碳基团α位点引入掩蔽羰基的新方法。因此,1与苯化物在酸性条件下反应,然后在甲醇中进行MPC处理和氢化物还原,得到2α-羟基-3, 3-二甲氧基衍生物,产率为57%。该产物在四个步骤中转化为共轭酮,产率为72%。该化合物的羧甲氧基通过CaCl2-二甲基亚砜-3-乙基戊烷-3-硫醇法去除,得到烯酮4,产率为70-80%,并异构化为共轭酮25c,产率为100%。最终,该化合物在四个步骤中转化为天然的赤霉碱(±)-依索碱(5),产率为31%,并进一步转化为(±)-依索丁(6)。
  • Synthesis of the Erythrina Alkaloid Erysotramidine
    作者:Chloé L’Homme、Marc-André Ménard、Sylvain Canesi
    DOI:10.1021/jo501583c
    日期:2014.9.5
    A concise synthesis of erysotramidine (an alkaloid belonging to the erythrina family) was achieved starting with an inexpensive phenol and amine derivative. The synthesis is based on oxidative phenol dearomatizations mediated by a hypervalent iodine reagent and includes a novel route to a key indolinone moiety.

  • A Concise Approach to Tetracyclic Spiroamine Scaffold of Erythrinan Alkaloids via an Oxidative Dearomatization-Spirocyclization Sequence
    作者:Masahisa Nakada、Emi Saito、Akihiko Nakamura
    DOI:10.3987/com-14-s(k)95
    日期:——
    This paper describes a novel synthetic approach to 11,12-dimethoxy-8,9-dihydro-1H-indolo [7a,1-a] isoquinoline-2,6-dione, which is a key synthetic intermediate to some erythrinan alkaloids. This concise approach features an oxidative dearomatization-spirocyclization sequence mediated by phenyliodine (III) bis(trifluoroacetate) (PIFA) that efficiently forms the tetracyclic spiroamine scaffold. An unusual solvent effect in the oxidative dearomatization-spirocyclization sequence is also described.
