Camphoric acid derived sulfur containing bicyclic carboxylic acids as chiral auxiliaries in N-acyliminium ion chemistry

Three novel sulfur containing chiral bicyclic carboxylic acids were synthesized from d-camphoric acid. Two of these compounds were briefly evaluated for their potency as chiral auxiliaries in Asymmetric Electrophilic α-Amidoalkylation (AEαA) reactions.
