This study presents the alkali metal mediated magnesiation (AMMMg) of three N‐alkylated indoles with the mixed Na/Mg base [(TMEDA)Na(TMP)2Mg(CH2SiMe3)] 1 (TMEDA = N,N,N′,N′‐tetramethylethylenediamine, TMP = 2,2,6,6‐tetramethylpiperidine). All three magnesiated indoles have been successfully characterised by single‐crystal X‐ray diffraction and solution state NMR studies, whereas iodolysis and Pd‐catalysed

Herein we describe a general, mild and scalable method for deuterium incorporation by potassium methoxide/hexamethyldisilane-mediated dehalogenation of arylhalides. With CD3CN as a deuterium source, a wide array of heteroarenes prevalent in pharmaceuticals and bearing diverse functional groups are labeled with excellent deuterium incorporation (>60 examples). The ipso-selectivity of this method provides
在此,我们描述了一种通过甲醇钾/六甲基乙硅烷介导的芳基卤化物脱卤来掺入氘的通用、温和且可扩展的方法。以 CD3CN 作为氘源,广泛存在于药物中并具有不同官能团的杂芳烃被标记为具有优异的氘掺入(> 60 个例子)。这种方法的 ipso 选择性提供了对氘代吲哚和喹啉库的精确访问。我们方法的合成效用已通过将氘掺入复杂的天然和类药物化合物中得到证明。
One-Pot Sequential Propargylation/Cycloisomerization: A Facile [4+2]-Benzannulation Approach to Carbazoles
A novel one‐pot [4+2]‐benzannulation approach to substituted carbazoles is accomplished by acid‐catalyzed C3‐propargylation of 2‐alkenyl/aryl indoles with 1‐aryl propargylicalcohols, followed by cycloisomerization. A variety of 2‐alkenylated indoles and 2‐aryl/heteroaryl indoles successfully participated in this tandem reaction with 1‐aryl/heteroaryl propargylicalcohols to provide diversely substituted

日期:——
development of a method for the Pd(II)-catalyzed denitrogenative coupling of arylhydrazines to give functionalized biaryls in good yield, using aryl bromides or aryl iodides as convenient and inexpensive aryl sources, is reported. High functional group tolerance is demonstrated for electronically distinct arylhydrazines as well as arylhalides. The desired products were isolated in good to excellent yields
