Asymmetric N-Acyliminium Cyclization as an Approach to Heterocyclic Natural Product Synthesis

This paper describes the development of a highly stereoselective N-acyliminium cyclization protocol for the construction of a range of non-racemic heterocyclic templates. Due to the nature of this review, we have focused primarily on developments made within our own research group, but have included relevant and noteworthy contributions in the same area from others, most notably the research groups of Amat, Bosch and Lete. As a result, we apologize in advance for the omission of much excellent work carried out by many other talented researchers in this field.
