Question 1 Alkylation of valerolactim ethers (1) is an attractive route to a-alkyl-ô-amino acids; important building blocks for medicinally important compounds. After discussion with your supervisor you decide to test two compounds, lithium diisopropylamide (LDA) and n-propyllithium (n-PrLi), as possible metalating reagents. The strategy is To synthesise fresh solutions of LDA and n-PrLi. To test them in reactions with the valerolactim ether (1) To obtain the possible cyclic chiral product on alkylation with benzylbromide LOME valerolactim ether (1)
