Expeditious Synthesis of the Polypropionate Sector of Rifamicyn S by Reiterative Diene-Aldehyde Cyclocondensation Reactions

Two Lewis acid catalyzed cyclocondensation reactions of activated dienes with β-oxygenated aldehydes are used in a rapid synthesis of the C19-C29 polypropionate sector of rifamycin S.Both processes occur with essentially perfect diastereofacial selectivit
