Here, we have reported a short and efficient BF3Et2O catalyzed synthesis of indolizidine derivatives. Morever, we have expanded this strategy to synthesize oxa-aza-cyclic derivatives. The stereochemistry of the indolizidine derivative 16 was confirmed by X-ray studies.

For the study on the structure-activity relationship of pyrilamine-based histone deacetylase inhibitor 1, we focused on the structures of its benzyl and dimethylamino groups. Of the synthesized novel pyrilamine derivatives 27, compound 2 enhanced potency against hERG inhibition, as well as decreased molecular weight and topological polar surface area.
