Here we report a strategy for carbonyl addition with unactivated alkenes using an organic photocatalyst on both aldehyde and ketone substrates. This protocol grants us a good alternative to the traditional Barbier–Grignardallylation that exhibits poor functional group tolerance. With this method the stoichiometric use of metals can be avoided, high atom economy can be achieved and fewer by-products

substituted with acetoxy groups on one, two, or three aromatic rings in the para and/or meta positions, were synthesized. The identity of the occurring E and Z isomers were established by 1H NMR spectroscopy. A study on structure-activity relationships was carried out with regard to estradiolreceptoraffinity and to inhibiting effects on the growth of a postmenopausal human mammary carcinoma implanted
