标题:Process for the synthesis of curcumin-related compounds
发明人：KRACKOV MARK HARRY; BELLIS HAROLD EDWARD
权利人:GENE PRINT INC
摘要:The invention is directed to a process for the synthesis of curcumin and curcumin-related compounds by reacting the enol form of a 2,4-diketone with a monocarbocyclic aldehyde in the presence of an organic amine catalyst. The reactants are dissolved in a highly polar, aprotic organic solvent. The curcumin-related product is recovered in crystalline form by precipitation from the reaction mass and solvent recrystallization.

标 题 :Nucleophilic fluoroalkylation of aldehydes
发明人：STAHLY G PATRICK
权利人:ETHYL CORP
摘要:Aryl difluoromethyl sulfone adds to aldehydes under phase transfer conditions to give novel substituted alcohols of the general formula n n RCH(OH)CF.sub.2 SO.sub.2 Ar (I) n n wherein R is an aryl, cycloaliphatic, sec- or tert-aliphatic, or heterocyclic group and Ar is an aryl group. The substituted alcohols of formula I are of particular utility as intermediates in the synthesis of a variety of useful end products. For example, the products of formula I may be utilized in desulfonylation reactions, oxidation reactions and fluorination reactions.
