Abstract
The 1,3-dipolarcycloaddition reaction of 1-methyl-1,2,3,4-tetrahydropyridine (1) with organic azides 2 affords 1-methylpiperidylidene-2-sulfon(cyan)amides 4 in high yield. The reaction proceeds via a 2,3,4,9-tetrazabicyclo[4.3.0]non-3-ene intermediate. Acid hydrolysis of 4d gives rise to 1-methyl-2-piperidone.
