Substituted Lithium (E)-3-Lithio-3-tosyl-2-propenolates: Useful Intermediates in Organic Synthesis
The lithiation of substituted tosylated epoxides 7 derived from allylic sulfones with methyllithium leads to lithium (E)-3-lithio-3-tosyl-2-propenolates 5 in a stereoselective manner.The further reaction of these intermediates with different electrophilic

OXIDATION REGIOSELECTIVE DE SULFONES ALLYLIQUES CATALYSEE PAR LE PALLADIUM ET LA LUMIERE: FORMATION D'ALDEHYDES ET ALCOOLS α,β-ETHYLENIQUES β-SULFONYLES
The irradiation of oxygenated solution of allyl sulfones containing small amounts of palladium trifluoroacetate led to regioselective oxidation of the allylic position furthest from the electron-withdrawing group.The efficiency of this reaction increased
