摘要:已经测量了从广泛的路易斯碱硼烷加合物中置换 Bh 3的奎宁环动力学.这些速率的参数化使得能够开发出离核量表 (Nf B),以量化和预测一系列其他路易斯碱基的离去基团能力.在多个系列 R' 3-N R N X (X = P,N; R' = 芳基,烷基) 中观测到的可加性允许制定相关的取代基参数 (N F Pb,N F Ab),提供了一种方法计算n F B一系列路易斯碱基的值远远超出了实验得出的值.通过取代基参数n F Pb与一系列烷基和芳基 Mida 硼酸盐在中性条件下的水解速率的相关性,探索了核离性参数的效用.这允许鉴定具有接近反应中心的杂原子的 Mida 硼酸盐,显示出不寻常的动力学不稳定性或水解稳定性.

标题 :Azetidinone alcohol disulfides and process for cyclization
发明人：KUKOLJA STJEPAN; PFEIL JANICE L
权利人:LILLY CO ELI
摘要:Azetidinone alcohol disulfides are synthesized by reduction of the corresponding aldehydes. The azetidinone alcohol disulfides are the substrates for a process which cyclizes these compounds to 1-oxa β-lactam compounds, employing a cyclizing reagent chosen from the class consisting of divalent mercury salts or trivalent phosphine compounds. The 1-oxa β-lactam compounds produced by this process are intermediates in the synthesis of 1-oxa β-lactam antibiotics.
