Mild basic treatment of (1R,4S)-2-endo-hydroxy-10,10-dinitrofenchane (5) led to (1R,4S)-2-exo-hydroxy-10,10-dinitrofenchane (6). The participation of the 10,10-dinitro group is essential for the epimerization to take place.
(1R,4S)-2-endo-hydroxy-10,10-dinitrofenchane(5)的温和碱性处理导致(1R,4S)-2-exo-hydroxy-10,10-dinitrofenchane(6)。10,10-二硝基基团的参与对于发生差向异构化是必不可少的。
