Wittig reactions in the ionic solvent [bmim][BF4]

The ionic salt [bmim][BF4] is an attractive solvent for Wittig reactions, allowing both easier separation of alkenes from Ph3PO together with eficient reuse to the solvent.

New Insights on the Reaction of Alkyl 3-Oxo-4-(triphenylphosphoranylidene)butanoate and Aldehydes under Concentrated Condensation Conditions. One-Pot Synthesis of Highly functionalised 6-Oxocyclohex-4-ene-1,3-dicarboxylates

New annulation methodologies for the construction of substituted cyclohex-2-enones are important in organic synthesis. In this paper wee describe a new one-pot synthesis of substituted cyclohexenonedicarboxylates in maximum yield of 52 percent from the condensation of alkyl 3-oxo-4-(triphenylphosphoranylidene)-butanoate 1 and aldehydes.

ACTION DES COMPOSES ORGANOMAGNESIENS SUR LES PYRONES-2 - VII ETUDE DE LA STABILITE RELATIVE DES HYDROXY-6 DYHIDRO-5,6 2H-PYRANNES ET DES CETOLS TAUTOMERES CORRESPONDANTS

In the reaction between organomagnesium compounds and 2-pyrones, the relative stability of the 6-hydroxy 5,6 2H-pyrans and their tautomeric forms (ketols) has no influence on the reaction pathway.When ethylenic ketols are obtained, the corresponding tautomeric dihydropyranols are prepared in a selective way by reaction of nucleophilic reagents on the 3,6-dihydropyrones.In the other hand, the exclusive formation either of the dihydropyranols or of the unsatured ketols E, during these two reactions, shows up that here is no equilibrium between these two entities in the experimental conditions.
