3-mesyloxy-, 3-acetoxy-, and 3-acetamidoquinuclidine-3-carbonitrile, respectively, by treatment with base. Treatment of 3-acetamidoquinuclidine-3-carbonitrile (3) with potassium hydride resulted in decyanation whereas alkyllithium reagents attacked the cyano group in 3 to produce the corresponding imines. Oxidative cyclization of the N-benzylated derivative of 3 with palladium acetate gave the tetracyclic
通过用碱处理,分别由3-甲酰氧基-,3-乙酰氧基-和3-乙酰酰胺基喹核苷-3-甲腈合成了具有3-螺氧基化的氧杂噻吩啉,呋喃酮和吡咯烷酮杂环的新的奎尼丁衍生物。用氢化钾处理3-乙酰氨基喹啉环-3-甲腈(3)导致脱氰,而烷基锂试剂攻击3中的氰基以产生相应的亚胺。用乙酸钯将3的N-苄基化衍生物氧化环化,得到四环化合物5-乙酰基-1,4-乙醇-1,2,3,4,5,6-六氢苯并[ c ] -1,5-萘啶。
