Here, we report a continuous flow protocol for the [3 + 2] cycloaddition of nitrones, in situ generated from oximes, into bicyclic isoxazolidines. This thermal process required very high temperatures to be efficient that were not easily reached in conventional reactors. A couple of examples are presented and in both the flow process showed a greater performance than the batch mode. The process intensification study allowed the generation of 120 g/h of a key pharmaceutical intermediate.
