This thesis is the use of commercially available methyl 2-iodobenzoate as the starting material and was prepared into iodine - oxazoline compound 118. Then, we undergo copper-catalyzed cross-coupling reactions of compound 118with thiols, and were readily facilitated to afford the corresponding desired products 127¡B136 in good to excellent yields. This method not only modified short- comings of that adding strong base to synthesis of sulfur-oxazoline ligands in past years but also has a good yield performances, the yield is 70 -87%. And we will use this strategy to undergo one pot reaction of carbon-sulfur coupling in future. In the end, we used new sulfur-oxazoline ligands127¡B128 in the Pd-catalyzed asymmetric alkylation of 1,3-diphenyl-2-propenyl acetate with dimethyl malonate. and reaction ee% were high, with the best result of 99% and 93% conversion.
