A diastereoselectiveorthoesterJohnson–Claisenrearrangement has been employed in the synthesis of both enantiomers of arundicacid, a potentialtherapeuticagent against Alzheimer'sdisease. The effect of solvent, olefin geometry and alcohol chirality on the diastereoselectivity of the orthoesterJohnson–Claisenrearrangement of a tartrate-basedallylalcohol has been studied.
