The invention discloses an improved process for the preparation of 2,2,5,5-tetrasubstituted hexane-1,6-dicarbonyl compounds, and in particular diethyl 2,2,5,5-tetramethylhexanedioate and dimethyl 2,2,5,5-tetramethylhexanedioate, by the alkylation of 1,2-difunctional ethane compounds with enolates of carbonyl compounds. The process provides higher yields and greater synthetic brevity than existing processes.
该发明披露了一种改进的工艺,用于制备2,2,5,5-四取代己烷-1,6-二酮化合物,特别是通过将1,2-二官能乙烷化合物与羰基化合物的烯醇酸盐进行烷基化来制备二乙酯-2,2,5,5-四甲基己二酸和二甲酯-2,2,5,5-四甲基己二酸。该工艺提供了比现有工艺更高的收率和更大的合成简洁性。
