Diastereoselective Synthesis of Highly Substituted Tetrahydropyran-4-ones
Clarke, Paul A.,Martin, William H. C.
, p. 4527 - 4529 (2002)
(Matrix Presented) Aldol reactions of β-ketoesters with aldehydes followed by a tandem Knoevenagel condensation, with a further equivalent of aldehyde, and intramolecular Michael addition produces single diastereomers of highly substituted tetrahydropyran-4-ones.
Investigation of the mechanism for the preparation of 6-phenyl-2,4- dioxotetrahydropyrans by the potassium carbonate promoted condensation between acetoacetate esters and benzaldehyde
Andersh, Brad,Nguyen, Elizabeth T.,Van Hoveln, Ryan J.,Kemmerer, Dylan K.,Baudo, David A.,Graves, Jessica A.,Roark, Mollie E.,Bosma, Wayne B.
, p. 4563 - 4567 (2013/06/05)
Treatment of benzaldehyde and an acetoacetate ester with potassium carbonate in an alcohol solvent proceeds via γ-C-alkylation rather than α-C-alkylation resulting in the formation of 6-phenyl-2,4- dioxotetrahydropyran. Based upon results from deuterium e
A short and convenient strategy for the synthesis of pyridazines via Diaza-Wittig reaction
Bel Abed, Hassen,Mammoliti, Oscar,Van Lommen, Guy,Herdewijn, Piet
supporting information, p. 6489 - 6491 (2013/01/15)
A convenient and selective synthesis of 6-substituted-4-hydroxy-3- methoxycarbonyl pyridazines has been developed via a diaza-Wittig reaction. The desired products substituted at the C6 position can be obtained from readily available starting materials under mild conditions. This represents an attractive new method for the synthesis of pyridazine derivatives.
Synthesis of multifunctionalized building blocks via vinylogous addition of Chan's diene to carbonyl and carbonyl-related electrophiles, mediated by molecular iodine
Villano, Rosaria,Acocella, Maria R.,Scettri, Arrigo
experimental part, p. 2768 - 2772 (2011/04/27)
The synthesis of multifunctionalized β-ketoesters has been achieved by using molecular iodine as a catalyst under very mild conditions. The vinylogous addition of Chan's diene 1 to carbonyl and carbonyl-related compounds (aldehydes, ketones, imines and acetals) occurred with high efficiencies and with complete γ-selectivity, giving a useful method for the synthesis of interesting libraries of different δ-functionalized β-ketoesters.
