3-Methoxalylchromone—a novel versatile reagent for the regioselective purine isostere synthesis
Satenik Mkrtchyan,Viktor O. Iaroshenko,Viktor O. Iaroshenko,Sergii Dudkin,Ashot Gevorgyan,Marcelo Vilches-Herrera,Gagik Ghazaryan,Dmitriy M. Volochnyuk,Dmitriy M. Volochnyuk,Dmytro Ostrovskyi,Zeeshan Ahmed,Alexander Villinger,Vyacheslav Ya. Sosnovskikh,Peter Langer +13 more
TL;DR: The first synthesis of 3-methoxalylchromone was described, where the reaction of the latter with electron-rich aminoheterocycles afforded a set of heteroannelated pyridines bearing a CO(2)Me substituent located at the α-position of the pyridine core.
Journal ArticleDOI
3-(Dichloroacetyl)chromone;A New Building Block for the Synthesis of Formylated Purine Isosteres:Design and Synthesis of Fused α-(Formyl)pyridines
Viktor O. Iaroshenko,Satenik Mkrtchyan,Gagik Ghazaryan,Ani Hakobyan,Aneela Maalik,Linda Supe,Alexander Villinger,Andrei A. Tolmachev,Dmytro Ostrovskyi,Vyacheslav Ya. Sosnovskikh,Tariel V. Ghochikyan,Peter Langer +11 more
TL;DR: The first synthesis of 3-dichloroacetylchromone from 3-dimethylamino-1-(2-hydroxyphenyl)propen-1-one and dichlo- roacetyl chloride is described in this paper.
Journal ArticleDOI
Synthesis of dichloromethyl-substituted salicylates and pyran-4-ones by cyclocondensation of 1,3-bis(silyloxy)-1,3-butadienes with 1,1-dimethoxy-4,4-dichlorobut-1-en-3-one: control of the C,C- and C,O-regioselectivity by the choice of Lewis acid
Vahuni Karapetyan,Satenik Mkrtchyan,Gagik Ghazaryan,Alexander Villinger,Christine Fischer,Peter Langer +5 more
TL;DR: The use of Me3SiOTf instead of TiCl4 resulted in a change of the regioselectivity and in the formation of functionalized 2-(dichloromethyl)pyran-4-ones.
Journal ArticleDOI
E/Z-Selective Synthesis of Alkylidene-3-oxo-3H-isobenzofurans by Reaction of Silyl Enol Ethers with Phthaloyl Dichloride
Satenik Mkrtchyan,Zorik Chilingaryan,Gagik Ghazaryan,Rüdiger Dede,Nasir Rasool,Muhammad A. Rashid,Alexander Villinger,Helmar Görls,Gnuni Karapetyan,Tariel V. Ghochikyan,A. S. Saghiyan,Peter Langer +11 more
TL;DR: In this paper, the reaction of silyl enol ethers with phthaloyl dichloride afforded alkylidene-3-oxo-3H-isobenzofurans with very good E/Z-selectivity.
Journal ArticleDOI
Synthesis of Dichloromethyl-Substituted Salicylates and Pyran-4-ones by Cyclocondensation of 1,3-Bis(silyloxy)-1,3-butadienes with 1,1-Dimethoxy-4,4-dichlorobut-1-en-3-one: Control of the C,C- and C,O-Regioselectivity by the Choice of Lewis Acid.
