  • Title: An aldol-based approach to the asymmetric synthesis of L-callipeltose, the deoxyamino sugar of L-callipeltoside A.
    Author: Evans DA, Hu E, Tedrow JS.
    Journal: Org Lett; 2001 Oct 04; 3(20):3133-6. PubMed ID: 11574013.
    Abstract:
    [reaction: see text] The L-callipeltose subunit of L-callipeltoside A has been synthesized in 10 steps and 13% overall yield from D-threonine. The key steps are a highly diastereoselective Felkin anti aldol addition to a methyl ketone and a selective methylation of a secondary alcohol in the presence of a secondary carbamate.
