Diyne macrocycles with different ring size were synthesized by developing a novel dual catalysis approach involving gold and copper catalysts through an intramolecular Glaser–Hay coupling reaction in good yield and demonstrated for a rapid total synthesis of ivorenolide B, a new class of macrolides endowed with a conjugated 1,3‐diyne motif, having impressive immunosuppressive activity.
通过开发新颖的涉及金和铜催化剂的新型双重催化方法,通过分子内的Glaser-Hay偶联反应以高收率合成了具有不同环尺寸的Diyne大环化合物,并证明了该类化合物具有的新的大环内酯类快速合成。共轭1,3-二炔基序,具有令人印象深刻的免疫抑制活性。
