Abstract: The spontaneous conversion of 3-indoxyl to indigo was a well-established process used to produce indigo dyes. It was recently shown that some indoles, when reacted with molybdenum hexacarbonyl and cumyl peroxide, proceed through an indoxyl intermediate to produce significant amounts of indirubin through a competing mechanism. Modulation of this system to lower temperatures allows for careful tuning, leading to selective production of indirubins in a general process. A systematic assay of indoles show that electron deficient indoles work well when substituted at the 5 and 7 positions. In contrast, 6-substituted electron rich indoles give the best results whereas halogeno indoles work well in all cases. This process shows broad functional group tolerance for generally reactive carbonyl-containing compounds such as aldehydes and carboxylic acids.

79% With yttrium(III) trifluoromethanesulfonate; at 100℃; for 0.166667h;Microwave irradiation; Ionic liquid; Green chemistry; General procedure: A 10 mL glass vessel suited for the monomode microwave oven was charged with 1 mmol substrate,1 mmol acid anhydride, 0.01 mmol metal triflate, and 1 mmol ionic liquid. Next, the vessel was sealedwith a Teflon cap and irradiated in a monomode microwave oven at many different reaction conditions(temperature and time) to find the optimal condition. Upon completion, the vessel was cooled down toroom temperature and the mixture was extracted with Et2O (5 × 10 mL). The ether layer was decantedand washed with water (2 × 10 mL), saturated aqueous NaHCO3 (2 × 20 mL), and brine (2 × 10 mL).The organic layer was dried over MgSO4, filtered, and the solvent was removed by a rotary evaporator.The isolated yield was determined after purification by flash chromatography (silica gel, n-hexane/ethylacetate, gradient 10:0 to 8:2).

75% With silver perchlorate; niobium pentachloride; In dichloromethane; at 0 - 30℃; for 4.3h; General procedure: In a round-bottom flask, an indole (153 mg, 1.3 mmol) was dissolved in a dry DCM (1.5 mL) at 0 C then the solution of acyl chloride (140 mg, 1 mmol) in DCM (1.5 mL) with syringe and 1 mol % of NbCl5 and 3 mol % of AgClO4 was added. The reaction temperature was then slowly increased to 30 C and the reaction was carried out at this constant temperature constantly. After 4 h the reaction was completed and monitored by TLC, then reaction mass was quenched by adding 5 mL water and extracted with ethyl acetate (2 x 15 mL). This subsequent extract was washed with water 10 mL, dried over anhydrous MgSO4 and evaported under vacuum. The purification of crude mass was done column chromatography on silica gel (100-200 mesh) by eluting with ethyl acetate and petroleum ether (10:90), which offered 3-benzoylindole (177 mg, 75 % yield) (Scheme-I). The yield of other indoles and acyl chlorides are given in Table-1.
Take SnCl4 (20 mmol) in a flask, 15 mL of toluene was added and the mixture was stirred in an ice-water bath. To the system was added acetyl chloride (20 mmol). After stirring for 0.5 h in ice-water bath, 2 mL of toluene was dissolved in 5-chloroindole (l0mmol), Was added dropwise to the reaction system, and the ice-water bath was stirred for 2h. TLC monitoring reaction completely, vacuum distillation to remove toluene, water and ethyl acetate extraction, combined organic phase, anhydrous magnesium sulfate drying. The magnesium sulfate was removed by suction filtration, and the filtrate was concentrated to recrystallize from absolute ethanol to give Compound 3.
