A diastereoselective orthoester Johnson–Claisen rearrangement has been employed in the synthesis of both enantiomers of arundic acid, a potential therapeutic agent against Alzheimer's disease. The effect of solvent, olefin geometry and alcohol chirality on the diastereoselectivity of the orthoester Johnson–Claisen rearrangement of a tartrate-based allyl alcohol has been studied.
