intramolecular 1,3-dipolar cycloaddition of the nitrile oxides derived from ω-nitroalkyl acrylates gave isoxazoline fused macrocyclic lactones. The direction of 1,3-dipolar cycloaddition is strongly affected by the ring size of forming lactones. Utilizing this method, total synthesis of (±)-A26771B was achieved.
源自丙烯酸ω-硝基烷基酯的腈氧化物的分子内1,3-偶极环加成得到异恶唑啉稠合的大环内酯。1,3-偶极环加成的方向受形成内酯环大小的强烈影响。利用该方法,实现了(±)-A26771B的全合成。
