90%	at 180℃; for 1 h; Neat (no solvent)	6-Carboxy-1-indanone used as the starting material of example 206 was prepared according to the following procedure: 3- (4-carboxyphenyl) propionic acid (5 g, 0.026 mol), frash AICI3 (25 g, 7.2 eq, 0.187 mol), and NaCI (2.5 g, 10percent w/w of AICI3 used) were loaded into a 100 mL flask fitted with a condenser and internal thermometer going to the bottom of the flask. The flask was shaken briefly to mix the solids, then heated in an oil bath set to 190 °C. Internal temperature was held at or above 180° C for 1 h (reaction will fuse to form a dark brown liquid), then the mixture was cooled, and washed with water into a 2000 mL beaker containing ice. 180 mL of 6 M HCI and 250 mL of EtOAc were added. The layers were separated and the aqueous layer extracted with EtOAc (3 x 200 mL). Combined organic layers were washed with 2 M HCI, water, and brine, dried with MgS04, filtered and concentrated in vacuo to yield 6-carboxy-1-indanone (4.10 g, 90percent) as a light brown solid directly used for the next step synthesis.

The reaction mixture was cooled to 25° C., the tacky mass was dissolved in ice-cold water and the solution was shaken with crushed ice in a 5 l glass beaker. A mixture of 600 ml of a 6 N HCl and 750 ml of ethyl acetate was added to the reaction mixture. The organic phase was separated off and the aqueous phase was extracted with ethyl acetate (3650 ml).

		To a solution of Example 20 (1.0 g, 3.92 mmol) in tetrahydrofuran (10 mL) at-78 C was added dropwise 2. 5M solution of n-butyllithium in hexanes (2.35 mL, 5. 88 mmol). Carbon dioxide gas was bubbled through the reaction mixture for about 5 minutes and the reaction mixture was warmed to 0 C. Cold water was added and the pH was adjusted to about 2 using 1N hydrochloric acid. The tetrahydrofuran was removed by rotary evaporation, the precipitate was collected by vacuum filtration and was washed with cold water to provide the desired product.

63%	With dipotassium hydrogenphosphate; [4,4?-bis(1,1-dimethylethyl)-2,2?-bipyridine-N1,N1?]bis [3,5-difluoro-2-[5-(trifluoromethyl)-2-pyridinyl-N]phenyl-C]iridium(III) hexafluorophosphate; 2,4,6-Triisopropylthiophenol; water-d2; triphenylphosphine; In dichloromethane; at 20℃; for 36h;Irradiation; Inert atmosphere; Sealed tube;	Weighed first (35.2mg, 0.2mmol), photocatalyst Ir[dF(CF3)ppy]2(dtbbpy)PF6 (2.3mg, 0.002mmol), Kappa2EtaRhoOmicron4 (34.8mg, 1.0equinu.), and Rhoh3Rho (0.22mmol, 57.6mg, 1.1equiv.) was added to the reaction tube, and the gas was exchanged three times through a vacuum line. Under an argon atmosphere, DCM/D2O (2.0 mL, 1: 1 nu/nu) was added. Then, 2,4,6-triisopropylthiophenol (0.03 mmol, 7.1 mg) was carefully added, and then the tube was sealed and placed under a 5W blue LEDs lamp and allowed to react at room temperature for 36 hours. At the end of the reaction. The reaction completed, the mixture was quenched with water, and extracted with DCM (3x10mL). Rotary evaporated organic phase was dried over anhydrous Na2SO4 the solvent was removed by dry-like, column chromatography (300-400 mesh silica gel chromatography) (eluent: petroleum ether - ethyl acetate, volume ratio: 40-10: 1) to give 20.3mg, 63% yield of product.
