A New ABCDE> Cycloaddition Strategy for the Approach to Yohimbe Alkaloids: Stereoselective Synthesis of (+/-)-3-epi-allo-Yohimbone

Diels-Alder cycloaddition between lactam-sulfone 9 and diene 10 led to adducts 11 + 12 (30:1, respectively).Compound 11 has been converted in 4 steps into (+/-)-3-epi-allo-yohimbone 16.Key words: Diels-Alder cycloaddition, Yohimbe alkaloids, (+/-)-3-epi-a

α,α'-Bisphenylthiocarbonyles en synthese organique; applications en serie indolique

α'α'-bisphenylthioesters have been prepared by a Michael reaction between methyl bisphenylthioacetate and unencumbered activated olefins.They have been transformed into monosulfenylated esters by thiophenol in the presence of a catalytic amount of base.Th
