Various optically active acetylenic alcohols (40-80percent e.e.) were obtained by enantioface-differentiating addition of lithium trimethylsilylacetylide to aliphatic aldehydes utilizing (2S, 2'S)-2-hydroxymethyl-1-<(1-methylpyrrolidin-2-yl)methyl>pyrrolidine as achiral ligand.Optically active (R)-1-trimethylsilyl-1-undecyn-3-ol 80percente.e.) was transformed into optically active 5-octyl-2(5H)-furanone in good yield.
