Diastereoselective access to the spirotetronate subunit of the quartromicins

The agalacto-spirotetronate B subunit of quartromicins was synthesized in a predictible manner, following the Claisen-Ireland/metathesis approach (CIM strategy). Ene-yne ring-closure and selective mismatch Sharpless dihydroxylation are discussed as key st
