efficient metal free self-sorting tandem protocol for stereospecificsynthesis of 2-thio-1,4-enediones involving C-C double bond formation via direct coupling of terminal alkynes has been developed. The method was also extended to the first synthesis of beta-thio-gamma-keto-alpha,beta-unsaturated esters via a cross coupling reaction with ethyl glyoxylate. The reaction relies on a first of its kind

[reaction: see text] A novel and efficient carbon-carbon double-bond formationreaction via coupling of aryl or heteroaryl methyl ketones has been developed. A dimethyl sulfoxide-iodine-CuO system was proven to be efficient for this reaction and afforded the expected products in good yields. A new synthetic strategy, a self-sorting tandem reaction, was involved in this type of reaction and was presented
