Unsymmetrical dialkenyl ketones were prepared from the reactions of alkenyl alkynyl ketones with 0.55 equiv of lithium dialkylcuprates.
Synthesis of 2-(hetero)aryl-5-(trimethylsilylethynyl)oxazoles from (hetero)arylacrylic acids
Pankova, Alena S.,Stukalov, Alexander Yu.,Kuznetsov, Mikhail A.
, p. 1826 - 1829 (2015/04/27)
A three-step method for the synthesis of 2-(hetero)aryl-5-(trimethylsilylethynyl)oxazoles is described. Easily accessible bis(trimethylsilyl)acetylene and acrylic acid derivatives are used as starting materials for the preparation of mono- and disubstituted 5-(trimethylsilyl)pent-1-en-4-yn-3-ones. Oxidative phthalimidoaziridination of these enynones provides the key 2-acyl-1-phthalimidoaziridines that are further utilized in the thermal expansion of the three-membered ring to furnish the target functionalizable oxazoles.
Synthesis of unsymmetrically 2,6-disubstituted 2,3-dihydrothiopyran-4-ones
Rosiak, Anna,Christoffers, Jens
, p. 5095 - 5097 (2007/10/03)
A series of 2,3-dihydrothiopyran-4-one derivatives with unequal substituents in the 2- and 6-position have been prepared by double conjugate addition of sulfide to enynones. These starting materials were accessed in two steps from terminal alkynes and α,β
