A flexible method for the synthesis of 2-substituted 1,2,5,6-tetrahydropyridines and piperidines from chloro-containing propargylamines
文摘
The stereoselective synthesis of 1,2,5,6-tetrahydropyridines is described. Aryl, alkyl, and α,β-unsaturated substituents at the 2-position are reported. The methodology can be extended to the synthesis of 2-substituted piperidines.
