(Figure Presented) The direct asymmetric allylic alkylation of β,γ-butenolldes with MBH carbonates to access γ,γ- disubstiltuted butenolldes containing adjacent quaternary and tertiary chiral centers has been presented In excellent stereoselectivities (86-96% ee, dr >95:5) and moderate to good yield (50-83%). Their synthetic utility has been well demonstrated by the facile construction of bicyclic lactones bearing 4-5 stereogenic centers. © 2010 American Chemical Soc.iety. Source
