1.1.1醇醛缩合反应 (Aldol condensation) Definition: An aldol condensation is an organic reaction in which an enol or an enolate ion reacts with a carbonyl compound to form a 3 hydroxyaldehyde or B-hydroxyketone, followed by a dehydration to give a conjugated enone. 定义:含有α-H的醛或酮,在稀碱或稀酸(通常为稀碱)的 催化作用下,一分子醛或酮的c氢原子加到另一分子醛 或酮)的氧原子上,其余部分加到羰基碳上,生成⑧羟基 醛或酮)的反应,该增长碳链的反应称为醇(羟)醛(酮)缩 合反应。1.1.1 醇醛缩合反应 (Aldol condensation) Definition: An aldol condensation is an organic reaction in which an enol or an enolate ion reacts with a carbonyl compound to form a β- hydroxyaldehyde or β-hydroxyketone, followed by a dehydration to give a conjugated enone. 定义：含有α-H的醛或酮，在稀碱或稀酸(通常为稀碱)的 催化作用下，一分子醛(或酮)的-氢原子加到另一分子醛 (或酮)的氧原子上，其余部分加到羰基碳上，生成β-羟基 醛(或酮)的反应，该增长碳链的反应称为醇(羟)醛(酮)缩 合反应
