Rearrangement of 5-(bromomethyl)-1-pyrrolinium salts into functionalized piperidines
摘要:
5-(Bromomethyl)-1-pyrrolinium bromides undergo rearrangement with alkoxides in the corresponding alcohol to afford 2,5-dialkoxypiperidines, which are easily converted into 3-alkoxypiperidines. 2,5-Dialkoxypiperidines undergo a peculiar thermal rearrangement to afford 5-alkoxy-1,2,3,4-tetrahydropyridines.
