Cycloadditions of the newly synthesized α-(4-[2.2]paracyclophanyl)-N-methyl nitrone (9) with selected dipolarophiles such as phenyl isocyanate (10), styrene (13), dimethyl acetylenedicarboxylate (15) and methylene sulfene (17) are reported. Two isolated diastereomeric oxadiazolones 11 and 12 are obtained by the reaction of 9 with 10, whereas the reaction of 9 with either 13 and/or 15 gives only one
新合成的α-(4- [2.2]对环苯甲酰基)-N-甲基硝酮(9)与选定的双极性亲和剂,如异氰酸苯酯(10),苯乙烯(13),乙炔二羧酸二甲酯(15)和亚甲基亚砜(17)的环加成反应被报道。通过9与10的反应获得两个分离的非对映异构的恶二唑酮11和12,而9与13和/或15的反应仅得到一个非对映异构体异恶唑14和/或16。通过9与17的反应获得4-([2.2] Paracylophanyl)-N-甲胺(20)。化合物的结构9,11和14是由X射线结构分析分配。
