Koike, Takeshi,Takeuchi, Naoki
, p. 484 - 488 (2002)
The reactions of sec-aminodienyl esters 3 with acetylacetone (4) afforded N-alkyl 3-acetyl-4-methoxycarbonylmethyl-2-methyl-1,4-dihydropyridines 5 and enamines 6, providing a new azaelectrocyclization reaction.
A new synthesis of N-alkyl 4-methyl-1,4-dihydropyridines utilizing sec-aminodienyl esters with crotonaldehyde
Koike
, p. 558 - 562 (2001)
The reactions of sec-aminodienyl esters 3 with crotonaldehyde (4) afforded N-alkyl 3-[2-(methoxycarbonyl)ethenyl]-4-methyl-1,4-dihydropyridines 5, providing a new azaelectrocyclization reaction.
Aminodienyl esters III: A new synthesis of 1,4-dihydropyridines by self- heterocyclic annelation reactions of sec-aminodienyl esters
Koike, Takeshi,Takeuchi, Naoki,Tobinaga, Seisho
, p. 1497 - 1500 (2007/10/03)
The reactions of sec-aminodienyl esters 3 in the presence of propargylaldehyde diethylacetal afforded 1,4-dihydropyridines. This provides a new self-heterocyclic annelation reaction.
