A convenient, one-pot synthesis of 2,3-diarylindoles 4 is described via a bis-Suzuki palladium-catalyzed cross coupling of 2,3-dihalo-1-(phenylsulfonyl)indoles 1 with arylboronic acids 2, followed by cleavage of the N-protecting group to give 4. The anti-inflammatory drug indoxole (4c) is prepared in high yield.
的2,3-diarylindoles一种方便,一锅法合成4经由2,3-二卤代-1-(苯基磺酰基)双-铃木钯-催化的交叉偶联吲哚描述1与芳基硼酸2,随后的裂解N-保护基给出4。以高收率制备抗炎药吲哚酚(4c)。
