Sugar amino acids at the anomeric position of carbohydrates: synthesis of spirocyclic amino acids of 6-deoxy-l-lyxofuranose
摘要:
Two anomeric spirodiketopiperazines and one spirohydantoin of 6-deoxy-L-lyxofuranose have been prepared from L-fucono-delta-lactone via ring contraction to the corresponding tetrahydrofuran carboxylate and anomeric functionalization including regioselective bromination and azide displacement.
