Aziridines in one step from hydantoins via Red-Al mediated ring-contraction
摘要:
We have developed a new method to synthesize aziridines from their corresponding hydantoins in one step using an excess of Red-Al overnight in refluxing toluene. This allows direct access to N-H aziridines without the need for protecting group strategies. (C) 2011 Elsevier Ltd. All rights reserved.

This paper describes a diamination process using di-tert-butyldiaziridinone as nitrogen source and CuCl as catalyst. A wide variety of disubstituted terminalolefins can be efficiently diaminated in good yields under mild condition. This diamination process was used to synthesize potent NK1 antagonist Sch 425078.
