Synthesis of 1,4-Diarylfluorenone and 1,4-Diarylfluorene
摘要:
A novel synthetic route to 1,4-diarylfluorenone and 1,4-diarylfluorene is presented by starting with ninhydrin. The retro-Diels-Alder cycloaddition was employed as a key step to construct the target fluorenones, while a highly efficient reduction from 1,4-diarylfluorenones to 1,4-diarylfluorenes is developed by using of sodium sulfide nonahydrate as reductant. The final products are confirmed by H-1 NMR, C-13 NMR and mass spectrometry.
