Tandem intramolecular Sakurai-aldol reactions provide a concise and highly diastereoselective route to substituted cyclohexenone derivatives. The cyclization substrates are readily obtained using olefin isomerization−Claisen rearrangement (ICR) reactions to prepare the key chiral allyl silane precursors. The Claisen reaction products are elaborated to the chiral Sakurai-aldol substrates by an efficient
