Epoxymethylation of 2-Acyl-Substituted NH Heterocycles and Transformations of the Epoxymethylation Products

Kharaneko, A. O.,Kharaneko, O. I.,Pekhtereva, T. M.

, p. 1677 - 1684 (2020)

Abstract: A new procedure has been proposed for the synthesis of previously unknown pyrrolo- and indolo-1,4-epoxy[1,4]oxazepines by epoxymethylation of 2-benzoyl-1H-pyrrole and 2-benzoyl-1H-indoles with epichlorohydrin. Some transformations of the epoxyme
