tandem strategy based on a Mannich/Pictet−Spengler sequence has been developed and additionally applied to the synthesis of a new small library (fourteen examples) of privileged compounds based on the spiro[piperidine-pyridoindole] core. The sequence proceeds via a diastereoselective Pictet−Spengler cyclization, after condensation of several tryptamine derivatives with three novel piperidin-4-ones containing

The advantages of performing reactions in continuousflow vs. the classic batch processes render flow chemistry a suitable technique for librarysynthesis. Inspired by our recent work to create fluorine-containing nitrogen heterocycles and
