An efficient synthesis of 5-(or 6-)-arylbenzoindolizidine and - quinolizidine derivatives

A new methodology for the synthesis of (hetero)arylated benzomdolizidine and benzoquinolizidine derivatives through sequential reduction of pyrrolidine- and piperidine-based aromatic enamides, and ultimate cyclization, is reported.

Dramatically different photochemical behaviour of 1-aroyl-2-methylene piperidine and pyrrolidine derivatives. An expeditious synthesis of ruspolinone

Upon irradiation in neutral solvent, the diversely substituted 1-aroyl-2-methylenepiperidines 6a-f give rise to photocyclized products 4a-f while their pyrrolidine congeners 7a,c,d afford enaminoketones 18a,c,d products of photo-Fries rearrangement.
