Chiral γ-lactones are prevalent organic architectures found in a large array of natural products. In this work, we disclose the development of a modified catalytic system utilizing a commercially available Cu-phosphite catalyst for the diastereoselective reductive coupling of chiral allenamides and ketones to afford chiral γ-lactone precursors in 80:20 to 99:1 dr.
手性γ-内酯是大量天然产物中普遍存在的有机结构。在本研究中，我们报道了一种改进的催化体系的开发，该体系利用市售的亚磷酸铜催化剂对手性烯丙酰胺和酮进行非对映选择性还原偶联，以80:20至99:1的非对映体比例得到手性γ-内酯前体。
