On April 18, 2014, He, Shuzhong; Hsung, Richard P.; Presser, William R.; Ma, Zhi-Xiong; Haugen, Bryan J. published an article.Synthetic Route of 14602-86-9 The title of the article was An Approach to Cyclohepta[b]indoles through an Allenamide [4+3] Cycloaddition-Grignard Cyclization-Chugaev Elimination Sequence. And the article contained the following:
A strategy for synthesizing highly functionalized cyclohepta[b]indoles through a concise [4+3] cycloaddition-cyclization-elimination sequence is described. The cycloaddition features nitrogen-stabilized oxyallyl cations derived from epoxidations of N-aryl-N-sulfonyl-substituted allenamides, while the cyclization and elimination employed an intramol. Grignard addition and a one-step Chugaev process, resp. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Synthetic Route of 14602-86-9
