Total synthesis of (–)-6,7-dideoxysqualestatin H5 by carbonyl ylide cycloaddition and cross–electrophile coupling

<p>The work presented in this thesis focuses on the total synthesis of (–)-6,7- Dideoxysqualestatin H5. Particular emphasis was the development of a cross– coupling strategy for direct delivery of the side chain towards the end of the synthesis.</p> <p>Various methods investigated...
