Indolizyl-5-lithium anions react with succinic and phtalic anhidrides giving 1,4-keto acids, with oxallyl chloride giving 1,2-diketone, and with ethyl pyruvate giving 1,2-hydroxyacid. However, with α-halocarbonyl compounds, they react in different ways, forming the products of selective bromination at C-5 (with α-bromo ketones and esters of α-bromo acids) and 5-chloroacetyl indolizines.
Indolizyl-5-锂阴离子与琥珀酸和邻苯二甲酸酐反应产生 1,4-酮酸,与草酰氯反应产生 1,2-二酮,与丙酮酸乙酯反应产生 1,2-羟基酸。然而,与 α-卤代羰基化合物以不同的方式反应,形成 C-5 选择性溴化产物(与 α-溴酮和 α-溴酸酯)和 5-氯乙酰茚茚。
