Several new piperidyl spirofused benzofurans and piperidyl spirofused benzopyrans were synthesized via an intramolecular radical cyclization as the key step. It was found that the yield of the formation of five-member ring was much higher than that of six
Synthesis of piperidine derivatives by reduction of pyridinium salts

, p. 3367 - 3379 (2008/02/13)
Piperidine derivatives 1a-e and 2a-f have been prepared by the reduction of 3-and 4-substituted pyridinium salts with NaBH4 in moderate to excellent yields. The reactions regioselectively give 1,2,5,6-tetrahydropyridines, and the yields depend greatly upon the nature of substituents on the phenyl ring and on the nitrogen atom, the nature and the position of the substituents on the pyridyl ring, and the chain length between the aryloxy and the pyridyl groups.
