Approaches toward Spirocompounds Using Tricarbonyliron Complexes

Han, Jeng-liang 11 July 2005 (has links)
We have successfully using the exocyclic double bond of tricarbonyliron triene complexes to undergo (2+1) and (4+2) cycloaddition for the rapid construction of spiro[2.5]octane and spiro[5.5]undecane system. These cycloaddition reactions were chemo-, regio-, and stereoselective. Synthetic studies toward Upenamide, Manzamine A and Manzamine J by using 1-cyano-2,4-cyclohexadiene tricarbonyliron complexes were also discussed.

Efficient iron-mediated approach to pyrano[3,2-a]carbazole alkaloids - first total syntheses of O-methylmurrayamine A and 7-methoxymurrayacine, first asymmetric synthesis and assignment of the absolute configuration of (−)-trans-dihydroxygirinimbine

Gruner, Konstanze K., Hopfmann, Thomas, Matsumoto, Kazuhiro, Jäger, Anne, Katsuki, Tsutomu, Knölker, Hans-Joachim 02 April 2014 (has links) (PDF)
Iron-mediated oxidative cyclisation provides an efficient approach to pyrano[3,2-a]carbazole alkaloids. Thus, improved routes to girinimbine and murrayacine as well as the first total syntheses of O-methylmurrayamine A and 7-methoxymurrayacine are reported. Asymmetric epoxidation of girinimbine led to (−)-trans-dihydroxygirinimbine and the assignment of its absolute configuration. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

First total synthesis of the biscarbazole alkaloid oxydimurrayafoline

Börger, Carsten, Krahl, Micha P., Gruner, Margit, Kataeva, Olga, Knölker, Hans-Joachim 07 April 2014 (has links) (PDF)
We report the first total synthesis of oxydimurrayafoline via nucleophilic substitution at the benzylic position at C-3 of the carbazole framework. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw. Nationallizenz frei zugänglich.
