halides gave, under reductive Heck conditions, the C‐aryl‐N‐phenyl‐substituted oxabicyclic imides 7a–c and 8a–c (Scheme 3). Domino‐Heck CC coupling reactions of 5, 6, and 1b with aryl or heteroaryl iodides and phenyl‐ or (trimethylsilyl)acetylene also proved feasible giving 8, 9, and 10a–c, respectively (Scheme 4). Reduction of 1b with LiAlH4 (→11) followed by Heck arylation and reduction of 5 with NaBH4
与c 两个双环的C偶联,不饱和二羧酰亚胺5和6与芳基和杂芳基卤化物,得到,还原下的Heck条件下,Ç -芳基- ñ -苯基取代的oxabicyclic酰亚胺7A - Ç和图8a - Ç(方案3) 。Domino-的Heck Ç C偶联反应的5,6,和1b的与芳基或杂芳基碘化物和苯基-或(三甲基甲硅烷基)乙炔也证明给予可行8,9,和图10A - Ç,分别(方案4)。的还原1B用的LiAlH 4(→ 11),接着的Heck芳基化和还原的5用NaBH 4(→ 13),接着的Heck芳基化打开一个新的访问桥接perhydroisoindole衍生物12a中,b和14a中,b与潜在的药物活性(方案5和6)。
