The first synthesis of lupinacidins A and B, tumor cell invasion inhibitors of microbial origin, has been achieved in four operational steps from 3-methoxy-2-methyl-2-cyclohexenone via the Diels–Alder cycloaddition of a conjugated cyclohexadiene derivative with a juglone-derived sulfinyl quinone followed by sequential elimination of a sulfenic acid and ethylene to afford protected forms of the target
羽扇豆酸A和B(微生物来源的肿瘤细胞侵袭抑制剂)的首次合成已在四个操作步骤中实现,从3-甲氧基-2-甲基-2-环己烯酮通过共轭环己二烯衍生物与胡胶的狄尔斯-阿尔德环加成,从3-甲氧基-2-甲基-2-环己烯酮衍生的亚磺酰基醌,然后依次消除亚磺酸和乙烯,得到目标分子的保护形式。
