反式-2-取代硫代氨基脲基-4-芳基-5,5-二甲基-2-氧-1,3,2-二氧磷杂环己烷的立体选择性合成及立体化学研究: 2006年; 首先合成了重要的磷酰异硫氰酸酯中间体3,然后便捷、高产率且立体选择性地合成了反式-2-取代硫代氨基脲基取代的新型六元磷杂环,其立体化学通过2DNOESYNMR确证.所有合成的化合物均进行了元素分析和光谱表征,其中目标产物的13CNMR表征为1,3,2-二氧磷杂环己烷衍生物的碳骨架表征提供了难得的依据.在溶剂DMSO-d6中,所有产物均异构化,生成磷原子的差向异构体.这一研究结果证明了C4-H以及31PNMR谱图与立体结构的相关性.; 冯德鑫陈茹玉黄有; 关键词：硫代氨基脲差向异构体

Regioselective and Stereoselective Synthesis of the 3-Aryl-4- phosphoryl-1, 2, 4-triazoline-5-ones: 2006年; A novel and efficient route of synthesizing 1, 2, 4-triazoline-5-ones is reported. The title compounds can be prepared in high yield and purity by the one-pot oxidation and cyclization of 1-acylthiosemicarbazides. The reaction is regioselective and stereoselective. The reaction condition is mild.; De Xin FENG Ru Yu CHEN You HUANG; 关键词：环化作用
