The utility of lithium t-butyl-N-tosyloxycarbamate (LiBTOC) as a (+)NHBOC synthon in highly diastereoselective reactions with chiral cis-aminoindanol derived amide cuprates is described. The diastereoselectivities of these reactions ranged from 96% to greater than 99%. The subsequent transformation of these adducts to α-amino acids is also described.
