Enantioselective formal aza-Diels-Alder reactions of enones with cyclic imines catalyzed by primary aminothioureas

A highly enantio- and diastereoselective synthesis of indolo- and benzoquinolizidine compounds has been developed through the formal aza-Diels-Alder reaction of enones with cyclic imines. This transformation is catalyzed by a new bifunctional primary aminothiourea that achieves simultaneous activation of both the enone and imine reaction components.
Room temperature hydroalkylation of electron-deficient olefins: sp 3 C-H functionalization via a Lewis acid-catalyzed intramolecular redox event
Pastine, Stefan J.,McQuaid, Kevin M.,Sames, Dalibor
, p. 12180 - 12181 (2007/10/03)
A practical method for the intramolecular hydroalkylation of electron-deficient olefins has been developed. The direct transformation of benzylic, tertiary, and sterically hindered secondary sp3 C-H bonds into C-C bonds under the action of a catalytic amount of a variety of Lewis acids is described. The mechanism of these transformations is proposed to involve a tandem hydride transfer/cyclization sequence. Copyright
Highly enantioselective conjugate additions to α,β-unsaturated ketones catalyzed by a (salen)Al complex
Taylor, Mark S.,Zalatan, David N.,Lerchner, Andreas M.,Jacobsen, Eric N.
, p. 1313 - 1317 (2007/10/03)
Chiral (salen)Al complex 1a catalyzes the highly enantioselective conjugate addition of carbon-and nitrogen-based nucleophiles to acyclic α,β-unsaturated ketones. This methodology is tolerant of substantial variation of the ketone structure, providing acc
Syntheses of α,β-unsaturated carbonyl compounds from the reactions of monosubstituted ozonides with stable phosphonium ylides
Hon, Yung-Son,Lu, Ling,Chang, Rong-Chi,Lin, Sheng-Wun,Sun, Pei-Pei,Lee, Chia-Fu
, p. 9269 - 9279 (2007/10/03)
Ozonides derived from terminal alkenes reacted with 1.3 mol equiv. of stable phosphonium ylides to give (E)-αβ-unsaturated carbonyl compounds in good to excellent yields. No reducing agent is needed in the reaction. However, alkoxyalkyl-substituted ozonides afforded a mixture of (Z)- and (E)-αβ-unsaturated carbonyl compounds under similar condition. The E/Z isomeric ratio is affected by the position of the heteroatom in the substituent of the ozonides. The possible mechanism of this reaction will be discussed. (C) 2000 Elsevier Science Ltd.
Asymmetric hetero-Diels-Alder reaction of 1-alkyl-3-silyloxy-1,3-dienes with ethyl glyoxylate catalyzed by a chiral (salen)cobalt(II) complex
Li, Lian-Sheng,Wu, Yikang,Hu, Yun-Jin,Xia, Li-Jun,Wu, Yu-Lin
, p. 2271 - 2277 (2007/10/03)
The hetero-Diels-Alder reactions of 1-alkyl-3-(tert- butyldimethylsilyl)oxy-1,3-butadienes with ethyl glyoxylate catalyzed by chiral salen-metal complexes have been studied. With a cobalt(II) complex as the catalyst, the reaction of 1-(2-benzyloxyethyl)-3-(tert- butyldimethylsilyl)oxy-1,3-butadiene with ethyl glyoxylate gave the Diels- Alder product in 75% isolated yield with the endo:exo ratio >99:1 and the enantiomeric excess ≤52%. The effects of temperature, catalyst and solvent are also discussed.
