Abstract

4-Alkyl Hasntzch esters are good alkyl radical storage. The preparation of multisubstituted α,β-unsaturated carboxylic acid esters under photocatalytic redox conditions by 4-alkyl Hantzsch esters and Baylis-Hillman adducts was investigated. The reaction conditions are mild and no additional additives are required. The coupling products were obtained in moderate to good yields.
