Adding a certain compound to certain chemical reactions, such as: 103440-52-4, name is Methyl 2-Iodo-5-methylbenzoate, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 103440-52-4, name: Methyl 2-Iodo-5-methylbenzoate
General procedure: This kind of general experimental procedure is based on our already published procedure.13 The general procedure (GP) was carried out with ortho-iodoester 1a-d (105.0-136.0 mg, 0.40 mmol) and aldehyde 2a-k (195.0-313.0 mg, 1.6 mmol) in the presence of Pd(OAc)2 (5.0 mg, 5 mol%), Ag2O (111.3 mg, 0.48 mmol), and TBHP (257.1 mg, 2.0 mmol) allowing the reaction mixture to stir at 120 C for 12-20 h. Progress of the reaction was monitored by TLC until the ortho-iodoester 1a-d had completely reacted. Then the reaction mixture was removed from the oil bath and allowed to reach r.t. DCE (2 mL) and concd H2SO4 (1.0 mL) were added and the mixture was stirred at 60 C for 5 min to 2 h. Progress of the product formation was monitored by TLC until the reaction was complete. The mixture was quenched by the addition of aq NaHCO3 and then extracted with CH2Cl2 (3 * 15 mL). The combined organic layers were washed with brine, dried (Na2SO4), and filtered. Evaporation of the solvent under reduced pressure and purification of the crude material by silica gel column chromatography (PE/EtOAc) furnished the products 3 (57.0-86.0 mg, 55-69%). The products 3aa, 3ac, 3ai, 3aj, 3ak, 3ba, 3bc, 3be, and 3bj are reported in the literature.9
