In the presence of a catalytic amount of trityl perchlorate, 1,4-benzoquinone, quinone monoimides, or imidoquinones react with silyl enol ethers to produce the corresponding benzofuran or indole derivatives in high yields via the corresponding Michael adducts.
在催化量的高氯酸三苯甲基酯存在下,1,4-苯醌、醌单酰亚胺或亚氨基醌与甲硅烷基烯醇醚反应,通过相应的迈克尔加合物以高产率生成相应的苯并呋喃或吲哚衍生物。
