Synthesis of a C1-C21 subunit of the protein phosphatase inhibitor tautomycin: A formal total synthesis

The synthesis of a C1-C21 subunit of tautomycin is described. The convergent route employs enantioenriched allenylstannane and zinc reagents derived from (S)-3-butyn-2-ol methanesulfonate. These reagents react with appropriate aldehyde segments to yield s
