chiral dienol ethers provides a new route to alkoxydioxines (alkoxyendoperoxides). Depending upon substitution and geometry, the [4+2] cycloaddition is accompanied or even supplanted by [2+2] cycloaddition leading to alkene cleavage and/or ene-like reaction leading to allylic hydroperoxides. The diastereoselectivity of cycloaddition is ultimately limited by the conformational freedom of the dienol ether
向手性二烯醇醚中添加1 O 2为制备烷氧基二恶英(烷氧基内过氧化物)提供了一条新途径。取决于取代和几何形状,[4 + 2]环加成伴随或什至被[2 + 2]环加成所取代,导致烯烃裂解和/或类似烯的反应导致烯丙基氢过氧化物。最终,二烯醇醚底物的构象自由度限制了环加成的非对映选择性。
