Synthesis of poly-substituted tetrahydropyridines from Baylis-Hillman adducts modified with N-allylamino group via radical cyclization

An expedient method was developed for the synthesis of 1,4,5,6-tetrahydropyridines by radical cyclization protocol involving consecutive 1,5-hydrogen transfer and double bond isomerization process starting from Baylis-Hillman adducts.
