The lithium enediolate of acetic acid can be generated efficiently, as a 0.5 M solution in THF, using lithium amides prepared from n-butyllithium in THF and either diethylamine or 1,3,3-trimethyl-6-azabicyclo-(3.2.1)-octane (AZA). Its reaction with carbonyl compounds leads to the corresponding β-hydroxy acids in good to moderate yields. Better yields are usually obtained when these amines are added
使用由正丁基锂在 THF 中和二乙胺或 1,3,3-三甲基-6-氮杂双环-(3.2.1) 中制备的氨基化锂,可以有效地生成乙酸的烯二醇锂,作为 THF 中的 0.5 M 溶液-辛烷 (AZA)。它与羰基化合物的反应以良好到中等的产率产生相应的 β-羟基酸。当这些胺以亚化学计量的量加入时,通常会获得更好的产率。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
