Indole and its derivatives undergo smooth conjugate addition onto en-1,4-dione derived from isatin and acetophenone, in the presence of a catalytic amount of molecular iodine in acetonitrile under mild conditions to afford a novel class of 3-(1-(1H-indol-3-yl)-2-oxo-2-phenylethyl)indolin-2-one derivatives in good yields with high degree of 1,4-selectivity. Some of these compounds are found to exhibit
吲哚及其衍生物在温和条件下在乙腈中催化量的分子碘的存在下,平滑地共轭加成至衍生自Isatin和苯乙酮的en-1,4-dione,以提供新型3-(1-(1 H-吲哚-3-基)-2-氧代-2-苯基乙基)吲哚-2-酮衍生物具有良好的收率和较高的1,4-选择性。发现这些化合物中的一些表现出适度的抗菌和抗真菌特性。
