Ruthenium tetroxide generated in situ under the Sharpless conditions was applied to different hydrocarbons containing cyclopropane groups either spiroanellated or ring-fused. In all cases oxidation occurred exclusively at the positions α to the cyclopropyl group to give ketones. Ring cleavage was observed when such positions were tertiary.
将在Sharpless条件下原位生成的四氧化钌应用于不同的含环丙烷基团的烃,这些环丙烷基团是螺链烷烃化的或环稠合的。在所有情况下,氧化仅在环丙基的α位发生,得到酮。当这些位置是三级时,观察到环裂解。
