参考标题:Development Of A Synthesis Of A 2,3-Disubstituted 4,7-Diazaindole Including Large-Scale Application Of Ch3Li/ticl4-Mediated Methylation Of An Enolizable Ketone 作者:Franz J. Weiberth,Harpal S. Gill,George E. Lee,Duc P. Ngo,Frederick L. Shrimp,Xuemin Chen,Geoffrey D'Netto,Bryan R. Jackson,Ying Jiang,Narendra Kumar,Frederick Roberts,Evgeny Zlotnikov |发布日期:2015.7.17 摘要:The Chemical Development Of A 2,3-Disubstituted 4,7-Diazaindole Is Described. The Requisite Tertiary Carbinol Substrate Was Prepared Employing In Situ-Generated Ch3Ticl3 As A Chemoselective And Preferred Reagent Compared To Ch3Mgx For Methyl Addition To An Enolizable Ketone. The 4,7-Diazaindole Ring System Was Efficiently Assembled Via An Intramolecular Chichibabin Transformation. The Optimized Processes
