2-Aminopyrimidines in just two steps from ketones, acetylenes and guanidine via β,γ enones
Schmidt, Elena Yu.,Tatarinova, Inna V.,Ivanova, Elena V.,Trofimov, Boris A.
, p. 283 - 284 (2017)
Available β,γ-enones, the products of nucleophilic addition of ketones to phenylacetylene, react with guanidine in the KOH / DMSO system at 70?°C to give 2-aminopyrimidines in up to 72% yield.
15-[(Z)-Phenylmethylidene]-7,14-dioxadispiro[5.1.5.2]pentadecanes: Stereoselective one-pot assembly from cyclohexanones and phenylacetylene in a KOH/DMSO suspension
Schmidt, Elena Yu,Zorina, Nadezhda V.,Skitaltseva, Elena V.,Ushakov, Igor A.,Mikhaleva, Albina I.,Trofimov, Boris A.
supporting information; experimental part, p. 3772 - 3775 (2011/08/06)
Cyclohexanones react with phenylacetylene in a KOH/DMSO suspension (80°C, 1 h) to give unexpectedly phenylmethylidene dispirocyclic ketals, 15-[(Z)-phenylmethylidene]-7,14-dioxadispiro[5.1.5.2]pentadecanes, in 16-22% yields (along with the anticipated β,γ- and α,β-ethylenic ketones).
Transition-metal-catalyzed rearrangement of 1,1-(Oligomethylene)-4-aryl-2- butene-1,4-diols: Ring expansion vs. aryl group migration
Lange, Alex,Heydenreuter, Wolfgang,Menz, Helge,Kirsch, Stefan F.
scheme or table, p. 2987 - 2991 (2010/03/03)
The transition-metal-catalyzed rearrangement of 1,1-(oligomethylene)-4- aryl-2-butene-1,4-diols was investigated. In the presence of PdCl 2(MeCN)2 and Cu(OTf)2, a rapidly equilibrating 1,3-isomerization is followed by 1,2-
Process for the preparation of organic compounds with manganese cataylsts or the like
-
, (2008/06/13)
A process of the present invention produces an organic compound by allowing a compound containing an electron attractive group of following Formula (1): 1wherein Y is an electron attractive group; and Rb and Rc are each a hydrogen atom or an organic group, where Y, Rb and Rc may respectively be combined with each other to form a ring with an adjacent carbon atom, to react with a compound containing an unsaturated carbon-carbon bond of following Formula (2) or 2wherein Rd, Re, Rf, Rg, Ri and Rj are each a hydrogen atom or an organic group, where Rd, Re, Rf and Rg may respectively be combined to form a ring with one or two adjacent carbon atoms, and Ri and Rj may be combined to form a ring with adjacent two carbon atoms, in the presence of oxygen and a catalytic compound of a Group 5, 6, 7, 8 or 9 element of the Periodic Table of Elements to yield a compound of following Formula (3) or (8): 3wherein Z is a hydrogen atom or a hydroxyl group; and Y, Rb, Rc, Rd, Re, Rf, Rg, Ri and Rj have the same meanings as defined above. This process can efficiently produce a compound having an alkyl group or alkenyl group bonded at the alpha position of an electron attractive group, or a derivative thereof, by catalytic radical addition reaction.

THE PREPARATION β-KETOALDEHYDES
Ager, David J.
, p. 419 - 422 (2007/10/02)
β-Ketoaldehydes(7) were prepared by the addition of bromophenylthiotrimethylsilylmethane(6) to trimethylsilyl enol ethers(3) followed by a sila-Pummerer rearrangement and hydrolysis.
