  • Synthesen und chemische Reaktionen von α-Cyano-α-isocyanoalkansäureestern
    作者:Marco Bergemann、Richard Neidlein

    日期:1996.8
    Synthesis and Chemical Reactions of α -Cyano -α -isocyanoalkanoic Acids.Caretα-Cyano-α-isocyanoalkanoic acid esters 5 were synthesizedin very good yields starting from alkyl α-cyano-α-(formylamido)acetates 3 by alkylation of theappropriate enolates followed by dehydration with trichloromethylchloroformate(diphosgene)/triethylamine at low temperatures. Bromination of these estersgave α-cyano-α-(dibromomethylideneamino)alkanoicacid esters 6 in quantitative yields. Reduction of 6with magnesium led to 5.

    作者:Stefan Müller、Richard Neidlein
    DOI:10.1002/1522-2675(200207)85:7<2222::aid-hlca2222>3.0.co;2-5
    日期:2002.7
    The reactivity of 2-cyano-2-isocyanoalkanoates 2 in multi-component reactions was investigated. i.e.. in the Passerini reaction and the Ugi-four-component condensation (see Schemes 2 and 3, resp.). Interestingly the structure of the 2-cyano-2-isocyanoalkanoates 2 strictly limited the possible starting materials. Only the combination of aliphatic aldehydes, halogenated acetic acid derivatives. and nonaromatic amines gave satisfactory results, i.e., provided depsidipeptides 5 (Tables 3 and 4) and depsitripeptides 9 (Tables 6), respectively. Some of the products of the multicomponent reactions were transformed into crystalline compounds by decarboxylation (see Scheme 4). After fractional crystallization. the molecular structure of one of the decarboxylated depsitripeptides, i.e., of 10, was established by X-ray crystallography.
