Syntheses of hitherto unreported azepine- and azocine-annulated heterocycles have been developed in excellent yields via a catalyzed aromatic aza-Claisen rearrangement followed by ring-closing metathesis using Grubbs first-generation catalyst.
Sequential Aza-Claisen Rearrangement and Ring-Closing Metathesis as a Route to 1-Benzazepine Derivatives
A synthetic strategy based on sequential application of aza-Claisenrearrangement and ring-closing metathesis reaction as key steps has been developed for the synthesis of various 1-benzazepine derivatives of pharmaceutical relevance.
