hydrolysis delivered 2,3-disubstituted indoles. The halides bearing a strong electron-withdrawing group in the 4-position can undergo in situ basic hydrolysis to provide the corresponding indoles. Polysubstituted indoles can be prepared from substituted 2-halotrifluoroacetanilides with high regioselectivity.
CuI / l-脯氨酸催化的2-卤代三氟乙酰苯胺与β-酮酯和酰胺的交叉偶联,然后进行原位酸性水解,生成了2,3-二取代的吲哚。在4-位带有强吸电子基团的卤化物可进行原位碱性水解以提供相应的吲哚。可以由具有高区域选择性的取代的2-卤代三氟乙酰苯胺制备多取代的吲哚。

An efficient method for the synthesis of nitrogen heterocycles containing a cyclic amidine moiety has been developed. The process involves palladium‐catalyzed C(sp2)Hactivation and isocyanideinsertion starting with readily accessible ortho‐heteroarene‐substituted aniline derivatives under mild conditions.
The reaction of ethyl3-(o-trifluoroacetamidophenyl)-1-propargyl carbonates with formate anions in the presence of Pd(PPh3)4 affords 2-alkylindoles in good to excellent yields.
Sequential alkylation/cyclization/isomerization of ethyl 3-(o-trifluoroacetamidoaryl)-1-propargylic esters: a new route to 2-acyl- and 2-ethoxycarbonyl-3-alkenyl indoles
The reaction of ethyl 3-(o-trifluoroacetamidoaryl)-1-propargylic esters with ethyl iodoacetate or α-bromoacetophenone in the presence of K2CO3 in DMSO provides a new simple access to 2-acyl- and 2-ethoxycarbonyl-3-alkenyl indoles.
3-(邻-三氟乙酰胺基芳基)-1-丙酸酯与碘乙酸乙酯或α-溴乙酰苯的反应在DMSO中K 2 CO 3的存在下提供了新的简单途径获得2-酰基-和2-乙氧基羰基-3-烯基吲哚。
