An asymmetricsynthesis of the C1-C16 polyol subunit 2 of the macrolide antibiotic ossamycin (1) has been achieved through stepwise carbon-chain elongation reaction from D-glucose, based on a chiral pool approach. An outstanding point of this strategy is asymmetric induction by utilizing steric hindrance of neighboring groups. The stereogenic centers at the C4 and C5 positions of 2 were constructed
