摘要:A series of trifluoromethylated hexahydropyrimidines was synthesized using Preyssler heteropoly acid H14NaP5W29MoO110 encapsulated in a silica framework as the catalyst under solvent-free conditions. This synthesis requires short reaction times (1.5 h) and 80 °C under solven...

摘要:The chiral intermediates (+)-11 and (+)-12, are synthetized by using the diastereoselective three-center Michael addition of the chiral β-ketoester 4 to crotonaldehyde 5 allowing a new efficient entry into the synthesis of the Prelog-Djerassi lactone and related compounds.

摘要:Abstract(#br)The cross talk between different membrane receptors is the source of increasing research. We designed and synthesized a new hetero-bivalent ligand that has antagonist properties on both A 1 adenosine and μ opiate receptors with a K i of 0.8 ± 0.05 and 0.7 ± 0.03...

摘要:Abstract(#br)Modern organic synthesis focuses on the discovery and the development of stereoselective multiple bond-forming transformations allowing the creation of several covalent bonds in a single operation. Hence, the number of steps required to obtain a target molecule ...

摘要:Abstract(#br)The addition of the dianion of Johnson’s sulfoximine to α,ω-halogenoesters evolves by an intramolecular heterocyclization to provide a direct access to 2-alkylidenetetrahydrofurans bearing a chiral sulfur atom via domino addition–elimination/S N reactions.

摘要:Abstract(#br)The palladium hydride–iminium complex generated from Pd/C and triethylamine catalyses the isomerisation of allylic alcohols into carbonyl compounds, and Pd/C catalyses the conjugate reduction of activated double bonds using triethylamine as the source of the two...

摘要:Abstract(#br)2-Sulfonimidoylylidene tetrahydrofurans and 2-sulfonimidoylylidene-5-vinyl tetrahydrofurans were readily synthesized via a consecutive acylation/SN2 sequence with total regio- and chemoselectivity from Johnson's sulfoximine derivatives. The same consecutive reaction ...
