Asymmetric diels-alder reactions of sulfonyl-functionalized α,β-unsaturated ketones with cyclopentadiene catalyzed by chiral lewis acid
Pei, Wen,Wang, Yu-Guang,Wang, Yong-Jiang,Sun, Li
experimental part, p. 3383 - 3388 (2009/05/07)
Asymmetric Diels-Alder reactions of (E)-1-substituted sulfonyl-3-penten-2- ones with cyclopentadiene catalyzed by a chiral titanium reagent were investigated. The enantioselectivity was studied with different substituents in the position of sulfonyl moiet
(E)-2-Oxo-1-sulfonyl-3-alkenes as Reactive Hetero 1,3-Dienes. Absolutely endo-Selective Hetero Diels-Alder Reactions with Vinyl Ethers in the Presence of a Lewis Acid Catalyst

(E)-2-Oxo-1-sulfonyl-3-alkenes as new hetero 1,3-dienes undergo smooth hetero Diels-Alder reactions with vinyl ethers in the presence of Eu(fod)3 or TiCl2(i-PrO)2.The reactions are absolutely endo-selective producing 2,4-cis-3,4-dihydro-2H-pyrans in excel
Highly stereoselective double Michael cyclization of 1-phenylsulfinyl and sulfonyl analogues of the nazarov reagent
Spino, Claude,Deslongchamps, Pierre
, p. 3969 - 3972 (2007/10/02)
The base-catalyzed double Michael addition of the β-keto sulfoxide 5 with 2-carbomethoxy-2-cyclohexenone (1) proceeds, after elimination of the sulfoxide moiety during chromatography on silica, to give the dehydrodecalin adduct 6 with high stereoselectivi
