Synthesis of 2-unsubstituted imidazolones from bisamides via a one-pot, domino dehydration/base promoted cyclisation process
摘要:
A one-pot, domino process was developed as an alternative approach for the preparation of 2-unsubstituted imidazolones. The methodology utilizes readily accessible bisamides, which upon a dehydration/-cyclisation sequence produced imidazolones in good yields. The transformation relies on the compatibility of the dehydrating agent and base, and the reaction conditions tolerate various functional groups. (C) 2018 Elsevier Ltd. All rights reserved.
