  • A Titanium(III)-Catalyzed Reductive Umpolung Reaction for the Synthesis of 1,1-Disubstituted Tetrahydroisoquinolines
    作者:Hieu-Trinh Luu、Stefan Wiesler、Georg Frey、Jan Streuff

    日期:2015.5.15
    presented that gives direct access to 1,1-disubstituted tetrahydroisoquinolines. The reaction is a titanium(III)-catalyzed reductive umpolung process in which nitriles act as effective acylation agents. The method is highly chemo- and regioselective and is demonstrated in 20 examples. It is well-suited for the large-scale synthesis of functionalized tetrahydroisoquinoline products, which is exemplified in

    日期:2010.12.17
    The total synthesis of the erythrina alkaloid 3-demethoxyerythratidinone has been achieved via a strategy based on combined rhodium catalysis. The catalytic tandem cyclization effected by the interplay of alkynyl and vinylidene rhodium species allows for efficient access to the A and B rings of the tetracyclic erythrinane skeleton in a single step. The synthesis also features rapid preparation of the

    [reaction: see text] A new strategy for the synthesis of 3-demethoxyerythratidinone has been developed and is based on an extraordinarily facile intramolecular Diels-Alder reaction of a 2-imido-substituted furan. During the course of the synthesis, several novel acid-induced rearrangement reactions were encountered.

    Heating of cycloalkanone-2-carboxylate with β-arylethylamine, and oxalylation of the resulting enamino-ester followed by Lewis acid-catalyzed intramolecular cyclization afforded various erythrinan-type heterocycles in excellent yields. This method is widely applicable not only to the synthesis of erythrinans but also to that of A-nor and A-homo analogs and ring-D variants of erythrinan. The alkoxycarbonyl group on the products was readily removed by a new decarbalkoxylation method (heating with magnesium chloride-dimethyl sulfoxide combination). Thus, starting from 2-ethoxycarbonyl-4, 4-ethylenedioxy-cyclohexanone, the 2, 8-dioxo-erythrinan derivative (35) was synthesized in several steps in high yield, and was readily converted to the natural Erythrina alkaloid, 3-demethoxyerythratidinone.
    将环烷酮-2-羧酸酯与β-芳基乙胺加热,并对所得到的烯胺酯进行草酰化,随后经过路易斯酸催化的分子内环化反应,可以很好地获得多种红豆杉类杂环化合物。该方法不仅广泛适用于红豆杉类化合物的合成,还可用于A-去甲基和A-同源物以及红豆杉的环-D变体的合成。产品中的烷氧羰基团可以通过一种新的去羧基化方法(与氯化镁-二甲基亚硫酰胺的组合加热)轻松去除。因此,从2-乙氧羰基-4,4-乙烯基二氧环己酮出发,经过几步反应以高产率合成了2,8-二氧红豆杉派生物(35),并可以很容易地转化为天然红豆杉生物碱3-去甲氧基红豆杉啶酮。
