  • Lewis‐Acid‐Catalyzed (3+2)‐Cycloadditions of Donor‐Acceptor Cyclopropanes with Thioketenes
    作者:Grzegorz Mlostoń、Mateusz Kowalczyk、André U. Augustin、Peter G. Jones、Daniel B. Werz

    A series of dialkyl 2-methylidene tetrahydrothiophene-3,3-dicarboxylates was prepared from (tert-butyl)iso-propyl thioketene via Lewis acid catalyzed (3+2)-cycloaddition with D-A cyclopropanes. In all studied cases the (Z)-diastereoisomer was found as the main product.
    以(叔丁基)异丙基烯酮为原料,通过路易斯酸催化与DA环丙烷的(3+2)环加成反应制备了一系列2-亚甲基四氢噻吩-3,3-二羧酸二烷基酯。在所有研究案例中,( Z )-非对映异构体被发现是主要产物。

  • First Examples of Reactions of AzoleN-Oxides with Thioketones: A Novel Type of Sulfur-Transfer Reaction
    作者:Grzegorz Mlostoń、Tomasz Gendek、Heinz Heimgartner
    DOI:10.1002/(sici)1522-2675(19980909)81:9<1585::aid-hlca1585>3.0.co;2-n
    日期:1998.9.9
    The reactions of 1,4,5-trisubstituted imidazole 3-oxides 1a-k with cyclobutanethiones 5a,b in CHCl3 at room temperature give imidazole-2(3H)-thiones 9a-k in high yield. The second product formed in this reaction is 2,2,4,4-tetramethylcyclobutane-1,3-dione (6a; Scheme 2). Similar reactions occur with 1 and adamantanethione (5c) as thiocarbonyl compound, as well as with 1,2,4-triazole-4-oxide derivative 10 and 5a (Scheme 3). A reaction mechanism by a two-step formation of the formal cycloadduct of type 7 via zwitterion 16 is proposed in Scheme 5. Spontaneous decomposition of 7 yields the products of this novel sulfur-transfer reaction. The starting imidazole 3-oxides are conveniently prepared by heating a mixture of 1,3,5-trisubstituted hexahydro-1,3,5-triazines 3 and alpha-(hydroxyimino) ketones 2 in EtOH (cf: Scheme 1). As demonstrated in the case of 9d, a 'one-pot' procedure allows the preparation of 9 without isolation of the imidazole 3-oxides 1. The reaction of Ic with thioketene 12 leads to a mixture of four products (Scheme 4). The minor products, 9c and the ketene 15, result from an analogous sulfur-transfer reaction (Path a in Scheme 5), whereas the parent imidazole 14 and thiiranone 13 are the products of an oxygen-transfer reaction (Path b in Scheme 5).
