The described method, which is easy to scale up and exhibits good functional group tolerance, displays exquisite selectivity control for the preparation of two structurally different compounds starting from the same precursors under free radical conditions.engjournal articlehttps://doi.org/10.1021/acs.orglett.5c01990open access547Química orgánica (Química)2306 Química Orgánica
