α-Phosphoramidolithium substituted allylic carbanions are used as homoenolate reagents with benzophenone and give regioselectively α- or γ-hydroxyalkylation products. Replacement of lithium by magnesium leads to γ substitution almost exclusively. Acidic hydrolysis of the adducts is a novel route to γ-lactol.
α-磷酰胺基锂取代的烯丙基碳负离子与二苯甲酮一起用作均烯酸酯试剂,可选择性地产生α-或γ-羟烷基化产物。用镁取代锂几乎完全导致γ取代。加合物的酸性水解是制备γ-乳糖醇的新途径。
