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
Chelation-Controlled Facially Selective Cyclocondensation Reactions of Chiral Alkoxy Aldehydes: Syntheses of a Mouse Androgen and of a Carbon-Linked Disaccharide

Magnesium bromide in tetrahydrofuran catalyzes the cycloaddition of a variety of chiral alkoxy aldehydes with activated butadienes.The stereochemistry of these products is such that they can be rationalized as arising from a reacting conformer in which th
