Asymmetric induction in conjugate addition of new chiral γheterosubstituted-α,β-unsaturated α-lactones from L-glutamic acid was accomplished in high diastereoselectivity with the formation of trans(R,S)-adducts and was disclosed to serve as a versatile procedure for the asymmetric synthesis of antileukemic lignan lactones.
由L-谷氨酸共轭添加新的手性γ-杂取代-α,β-不饱和α-内酯的不对称诱导以高非对映选择性完成,形成反式(R,S)-加合物,并被公开作为一种通用的方法抗白血病木脂素内酯的不对称合成。
