Abstract
The highly efficient and convenient protocol to prepare diverse α, β-unsaturated aldehydes, ketones, and acids via the parallel solid-phase synthesis is developed. The key sulfone linker cleavage strategy is performed by ozonolysis to generate a carbonyl moiety followed by base-mediated polymer-bound sulfinate elimination to release our desired molecules from the resin. All α, β-unsaturated carbonyl compounds are prepared in good purities and ...
