We report the synthesis of four new oximes and three nitroalkanes bearing a chiral unit. All these compounds were converted into nitrile oxides and subjected to 1,3-dipolar cycloaddition with 3-E-hexene, giving the corresponding 2-isoxazolines in fair yields but only with moderate stereoselectivities.
我们报道了带有手性单元的四种新肟和三种硝基烷的合成。所有这些化合物均转化为腈氧化物,并与3- E-己烯进行1,3-偶极环加成反应,以适当的收率得到相应的2-异恶唑啉,但仅具有中等的立体选择性。
