Synthesis of Stereopentad Subunits of Zincophorin and Rifamycin-S through Use of Chiral Allenyltin Reagents
The anti,anti adduct 3, from addition of the allenic stannane (P)-2 to the α-methyl-β-OBn aldehyde (S)-1 promoted by SnCl4, was converted to the stereopentad 6 by a sequence involving reduction to the (E)-allylic alcohol with Red-Al, Sharpless asymmetric epoxidation, and addition of the higher-order...
