Side chain metalation at the 5-methyl or 5-benzyl position of 4,4-dimethyl-2-(5-substituted-2-furyl)oxazolines has been achieved using butyllithium as metalating agent and THF-HMPA 4:1 as solvent. The lithiated species can be reacted with various electrophiles to give the expected products in good yields.
使用丁基锂作为金属化剂,THF-HMPA 4:1作为溶剂,已实现了4,4-二甲基-2-(5-取代的-2-呋喃基)恶唑啉在5-甲基或5-苄基位置的侧链金属化。锂化的物质可以与各种亲电试剂反应,以高收率得到预期的产物。
