A highly enantioselective construction of δ- and γ-lactone[2,3-b]piperidine skeletons was accomplished by tandem aza-Diels–Alder reaction–hemiacetal formation–oxidation from N-Tos-1-aza-1,3-butadienes and aliphatic dialdehydes.
δ-和的高度对映选择性 γ-内酯[2,3- b ]哌啶通过串联氮杂-狄尔斯-阿尔德反应-半缩醛形成-N -Tos-1-氮杂-1,3-丁二烯和脂肪族二醛的氧化来完成骨架。
