The addition of chloral and bromal to a variety of alkyl-substituted alkenes has been investigated. The effect on the reaction of varying the Lewisacid catalyst and the structure of the substrate have been studied. Anhydrous AlCl3 was found to be the most effective catalyst, and ene-type adducts were the major products in most cases. Side reactions were observed with the less reactive systems leading
Development of copper-catalyzed enantioselective decarboxylative aldolization for the preparation of perfluorinated 1,3,5-triols featuring supramolecular recognition properties
properties to organic molecules but the scarcity of natural organofluorine sources renders the development of new synthetic methods highly desirable. Using a chiral BOX/Cu combination, enantioselective decarboxylative aldolization of perfluorinated aldehydes has been developed. Most notably, the reaction occurring under mild conditions and with high enantiocontrol can create ketodiols in one single synthetic
