Tandem conjugate addition-elimination for the diastereoselective synthesis of 4E-alkenyl syn-1,3-diols
Rotulo-Sims, Delphine,Prunet, Joelle
, p. 4147 - 4150 (2007)
We have developed a tandem conjugate addition-elimination sequence for the diastereoselective synthesis of protected allylic syn-1,3-diols, starting from vinyl sulfones. The sulfonyl group was then reduced with sodium amalgam to furnish the E-olefin as th
