compound introduction

甲基锂是一种有机锂试剂，主要用于去质子化和作为甲基阴离子的来源。它是一种强碱和强亲核体。 应用 在手性铜催化剂存在下，甲基锂水溶液（1.6 M 乙醚中）已用于烯丙基亲电试剂的不对称烯丙基烷基化反应。该方案导致具有高度对映选择性的三级和四级立体中心的 C-C 键形成。它也可用于在（ - ） - 鹰爪豆碱作为手性配体存在下与6,7-二甲氧基-3,4-二氢异喹啉反应而用于合成（ - ） - 猪毛菜碱。 Methyllithium is an organolithium reagent mainly used for deprotonation and as a source of methyl anion. It is a strong base and a strong nucleophile.
