The sequence begins with the treatment of 2-methylcyclohexanone with LDA to form an enolate, which is then reacted with ethyl chloroformate. The final step involves acidification, leading to the formation of a product. The goal is to determine the major product, which is (R)-2-ethoxycarbonyl-2-methylcyclohexanone, taking into account the stereochemistry of the reaction."}
