top of your chemistry! An “on water”, palladium‐catalyzed, phosphine‐free direct CH arylation of indoles, with iodoarenes at 25–30 °C, is disclosed (see scheme; TBDMS=N‐tert‐butyldimethylsilyl ether; SEM=N‐2‐(trimethylsilyl)ethoxymethyl; Bn=benzyl, Piv=pivabyl). The mildness of the reaction conditions permits the tolerance of a variety of N1‐protected indoles.
掌握化学反应!一个“水”,钯-催化的,游离的膦直接Ç ħ吲哚的在25-30℃的芳基化,与iodoarenes,公开了(参见方案; TBDMS = ñ -叔丁基二甲基醚; SEM = Ñ -2 -(三甲基甲硅烷基)乙氧基甲基; Bn =苄基,Piv =吡巴贝基)。反应条件温和性使得各种N1的宽容-保护的吲哚类化合物。
