the sodium salts of allyl alcohol and propargyl alcohol, respectively, were subjected to tri-n-butyltinhydride/AIBN free radical cyclization conditions. While the propargylic compound (15) did not cyclize, the allylic compounds (8, 28) cyclized in the presence of diphenyl diselenide, TEMPO or oxygen as radical trapping agents to give the corresponding 2,3-dihydrofuro[3,2-c]pyridine-4-carboxylic acid
