The macrocyclic ketone acerogenin C (3) and the corresponding alcohol (+)-accerogenin A (1), diarylheptanoid constituents of the maple Acer nikoense were synthesized. The key steps were the selective reduction of the double bond of an α,β-unsaturated ketone (10) and macrocyclization of an iodophenol (13) by a modified Ullmann diarylether synthesis.
合成了大环酮 acerogenin C (3) 和相应的醇 (+)-accerogenin A (1),合成了枫树 Acer nikoense 的 diarylheptanoid 成分。关键步骤是通过改进的 Ullmann 二芳醚合成选择性还原 α,β-不饱和酮 (10) 的双键和碘苯酚 (13) 的大环化。
