An efficient one-pot synthesis of optically active β-alkyl-substituted alcohols through a tandem copper-catalyzedasymmetricallylicalkylation (AAA) with organolithium reagents and reductive ozonolysis is presented. Furthermore, hydroboration–oxidation following the Cu-catalyzed AAA leads to the corresponding homochiral γ-alkyl-substituted alcohols.

Effective convergent syntheses of archaebacterial C40-diol [(3R,7R,11S,15S,18S,22S, 26R,30R)-octamethyldotriacontane-1,32-diol] and its (3S,7S,11R,15R,18R,22R,26S,30S)-enantiomer have been accomplished using (R)-5-acetoxy-4-methylpentanoic acid as the only chiral building block. Both synthetic schemes include consecutive construction of mono- and diterpene fragments of the target molecules followed
