As such, it is becoming recognised as an enabling technology for diversity-oriented synthesis. Herein, we provide a thorough account of our work combining two-directional synthesis with diversity-oriented synthesis, with particular reference to the synthesis of polycyclic alkaloid scaffolds. %K alkaloids %K cascade reactions %K chemical diversity %K diversity-oriented synthesis %K Lewis acid catalysis %K two-directional synthesis %U http://dx.doi.org/10.3762/bjoc.8.95
