Synthesis of pyridine derivatives by reactions of α,β-unsaturated nitriles with 2-oxo-cycloalkano carbothioic acid anilides

Krystyna Bogdanowicz-Szwed; Malgorzata Krasodomska; Malgorzata Lipowska; Barbara Rys; A. Skonecka

SummaryThe tandem Michael addition-cyclization of 2-oxo-cycloalkane carbothioic acid anilides1–3 to benzylidenemalononitrile4 yielded spiroannulated pyridines5–7. Reaction of acrylonitrile with2 and3 gave 2,2-disubstituted Michael adducts14,15, whereas with1 led to 2,2,5-tri(2-cyanoethyl)-cyclopentanone11.ZusammenfassungDie Michael Tandem-Addition-Cyclisierung von 2-Oxo-cycloalkano-thiokohlensäure-aniliden1–3 mit Benzylidenmalononitril4 ergab die spiroannelierten Pyridine5–7. Reaktion von Acrylnitril mit2 und3 ergab die 2,2-disubstituierten Michael-Addukte14,15, wohingegen mit1 2,2,5-Tri(2-cyanethyl)-cyclopentanon11 erhalten wurde.

Hetero-Diels-Alder reaction of some 1,3-diaza-1,3-butadienes with ketenes. Synthesis of functionalized pyrimido[1,2-b]-benzothiazoles and 1,3,4-thiadiazolo-[3,2-a]pyrimidines

Krystyna Bogdanowicz-Szwed; Malgorzata Krasodomska

SummaryReaction of 1,3-diaza-1,3-butadienes (1a–c) with various ketenes and chloroketenes results in the formation of substituted 4-oxo-pyrimido[2,1-b]benzothiazoles (4a–d) and 1,3,4-thiadiazolo[3,2-a]pyrimido-4-ones (4e,f). Reaction of 1,3-diaza-1,3-butadienes1d,e with ketenes and chloroketenes leads to the 2-morpholine-substituted compounds7 and15, respectively. All reactions proceedvia formation of [4+2] cycloadducts that eliminate methylthiol, methylsulfenyl chloride, or morpholine.ZusammenfassungDie Reaktion der 1,3-Diaza-1,3-butadiene1a–c mit verschiedenen Ketenen und Chlorketenen führt zu substituierten 4-Oxo-pyrimido[2,1-b]benzothiazolen (4a–d) und 1,3,4-Thiadiazolo[3,2-a]pyrimido-4-onen(4e,f). Die 1,3-Diaza-1,3-butadiene1d,e ergeben mit Ketenen und Chlorketenen die 2-Morpholin-substituierten Verbindungen7 und15. Alle Reaktionen verlaufen über [4+2]-Cycloaddukte, die Methylthiol, Methylsulfenylchlorid oder Morpholin eliminieren.

Reaction of 1-Oxa-4-aza-1,3-butadienes with Ketenes: Synthesis of Functionalized β-Lactams

Krystyna Bogdanowicz-Szwed; Malgorzata Krasodomska

Summary. The reaction of phenylimines derived from β-phenyl-α,β-diketopropionic acid ester (1a) β-phenyl-α,β-diketopropionic acid morpholide (1d), and α,β-diketobutyric acid morpholide (1c) with ketenes 2 in the presence of triethylamine yielded a mixture of diastereoisomeric azetidinones 3 and 4. The reaction of 3e with sodium borohydride involved the reduction of the benzoyl moiety affording hydroxy derivative 5. The structure of the obtained products was established on the basis of analytical and spectroscopic data.Zusammenfassung. Die Reaktion von aus β-Phenyl-α,β-diketopropionsäureester (1a), β-Phenyl-α,β-diketopropionsäuremorpholid (1b) und α,β-Diketobuttersäuremorpholid (1c) hergestellten Phenyliminen mit Ketenen (2) in Gegenwart von Triethylamin ergab Mischungen der diastereomeren Azetidinone 3 und 4. Die Reaktion von 3e mit Natriumborhydrid führte über eine Reduktion der Benzoylgruppe zum Hydroxyderivat 5. Die Struktur der erhaltenen Produkte wurde aus analytischen und spektroskopischen Daten abgeleitet.

Reaction ofSchiff bases of 1-tetralone with acid chlorides. Stereoselective synthesis of β-lactams spiroannulated with the tetrahydronaphthalene ring system

Krystyna Bogdanowicz-Szwed; Malgorzata Krasodomska

SummaryArylimines of 1-tetralone (1) react with various substituted acetyl chlorides (2) in the presence of triethylamine yielding β-lactams spiroannulated with tetrahydronaphthalene (3). The stereochemistry of the products has been determined by NMR methods. Reactions of imines1 with acid chlorides2 were proved to be highly stereoselective.ZusammenfassungArylimine von 1-Tetralon (1) reagieren in Gegenwart von Triethylamin mit substituierten Säurechloriden (2) zu mit Tetrahydronaphthalin spiroannellierten β-Lactamen (3). Die Stereochemie der Produkte wurde mittels NMR-Spektroskopie aufgeklärt. Es konnte gezeigt werden, daß die Reaktion hoch stereoselektiv verläuft.

Efficient synthesis of polyfunctionalised pyridines by conjugate addition of 2-thienylcarbonyl(thioacetanilides) to α/β-unsaturated nitriles

Krystyna Bogdanowicz-Szwed; Malgorzata Krasodomska

Conjugate addition of 2-thienylcarbonyl(thioacetanilides) (1) to arylmethylenemalononitriles (2) yielded 2-amino-1,4-diaryl-5-(2-thienylcarbonyl)-6-thioxo-1,4,5,6-tetrahydropyridine-3-carbonitriles (4), which when oxidised with HgO gave functionalised 2,6-dioxopiperidines (6), whereas with MCPBA they afforded pyrido[2,1-b]benzothiazole-2-carbonitrile derivatives (7).
