摘要:
报告了一种获得 N,N′-甲桥重氮喹硼烷的新串联路线,其中 7-氮杂苯并降冰片二烯与酯活化的 N-(甲氧基甲基)氮丙啶环丁烷反应生成加合物,加合物通过一个 N 桥的氮孤对与连接到相邻 N 桥的甲氧基甲基的亲核攻击立即形成 N,N′-甲桥。本文讨论了形成这种类型的 N,N′-甲桥结构的其他途径。

weak interactions with the entering and leaving groups. Secondary ..cap alpha..-deuterium isotope effects for the second-order reactions range from (k/subH//k/sub D/)/D = 0.99 for fluoride ion to 1.18 for iodide ion. Solvolysis and the second-order reaction with n-propylamine exhibit values of ..delta..S/sup + +/ = -1.2 and -2.1 cal K/sup -1/ mol/sup -1/, respectively, and display similarmore » changes

A new tandem route to N,N′-methano-bridged diazasesquinorbornanes is reported in which 7-azabenzonorbornadienes are reacted with ester-activated N-(methoxymethyl)aziridinocyclobutanes to form adducts which immediately undergo N,N′-methanobridge formation by nucleophilic attack of the nitrogen lone pair of one N-bridge onto the methoxymethyl group attached to the adjacent N-bridge. Alternative routes to N,N′-methano-bridged structures of this type are discussed.
