The dimeric metabolite acremine G was synthesized featuring a highly regioselective and stereoselective Diels−Alder reaction between a TBS-protected hydroquinone diene and a structurally related alkenyl quinone. The major endo [4 + 2] adduct slowly transforms to acremine G by the atmospheric air under the deprotection conditions (in situ generated HF).
合成的二聚体代谢产物顶峰G的特征在于TBS保护的对苯二酚二烯与结构相关的烯基醌之间具有高度区域选择性和立体选择性Diels-Alder反应。在脱保护条件(原位生成的HF)下,大气中的主要内含物[4 + 2]加合物缓慢转化为丙烯酰胺G。
