The use of lithioethylenediamine as a dehydrogenating and isomerizing reagent has been further extended and applied to new mono-, sesqui- and diterpenes. Structures of reaction products, including the phenol (XXVII), recently obtained as a degradation product of copaene, were decided on the basis of IR, UV and NMR spectral studies. Some of the transformations carried out with the help of this reagent
硫代
乙二胺作为脱氢和异构化试剂的用途已得到进一步扩展,并已应用于新的单,
倍半萜和二萜。基于IR,UV和NMR光谱研究,确定了最近获得的反应产物的结构,其中包括
苯酚(XXVII),其是作为可
戊烯的降解产物。在该试剂的帮助下进行的某些转化似乎无法通过任何其他已知试剂进行。
