Chiral, enantiopure 1,3-aminoalcohols, obtained through an organocatalytic Mannich reaction, have been used as inputs in a concise sequence involving diastereoselective Ugi reaction followed by various types of SN2 cyclization. In this way, different enantiopure heterocycles have been prepared, exploring both scaffold and decoration diversity (up to 4 diversity inputs).
