Abstract
[reaction: see text] Hetero-Diels-Alder reactions of Brassard diene with aromatic aldehydes were carried out smoothly in the presence of titanium(IV) tridentate Schiff base complexes to give the corresponding chiral delta-lactones in high enantioselectivities (up to 99% ee) under mild conditions.
摘要
[反应：见正文] 在三齿席夫碱钛（IV）配合物存在下，布拉萨德二烯与芳香醛的杂环狄尔斯-阿尔德反应顺利进行，在温和条件下以高对映选择性（高达99% ee）得到相应的手性δ-内酯。
