Water as a solvent for the Claisen rearrangement: practical implications for synthetic organic chemistry

Abstract: L'influence accelerante de l'eau comme solvant, sur la vitesse de la transposition de Claisen a ete demontree pour divers substrats

Diastereoselection in an aqueous Diels-Alder reaction: a formal total synthesis of the Inhoffen-Lythgoe diol

Abstract: A formal synthesis of the Inhoffen–Lythgoe diol (1) featuring a novel intermolecular Diels–Alder strategy wherein an intact C(20) stereocentre as part of a diene unit is used to elaborate directly the stereocentres at C(13) and C(17) of the hydrindan ring system of (1), is reported.
