Temperature controlled chemoselective dehydrogenation and aromatization of tetrahydro-β-carbolines, using molecular I2 and H2O2, in DMSO solvent affords a practical access to a series of corresponding 3,4-dihydro-β-carbolines and β-carbolines respectively. This method has been successfully employed in the short synthesis of Kumujian-C, Eudistomin-U, Norharmane Harmane Harmalan and Isoeudistomin-M.
在DMSO溶剂中使用分子I 2和H 2 O 2对四氢-β-咔啉进行温度控制的化学选择性脱氢和芳构化,可分别实际获得一系列相应的3,4-二氢-β-咔啉和β-咔啉。该方法已成功用于Kumujian-C,Eudistomin-U,Norharmane Harmane Harmalan和Isoeudistomin-M的短合成中。
