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.
Aminodienylesters. II. A new synthesis of 2,3-dihydro-6H-1,3-oxazines by heterocyclic annelation reactions of sec-aminodienylesters with acetaldehyde
Koike, Takeshi,Tanabe, Mituharu,Takeuchi, Naoki,Tobinaga, Seisho
, p. 27 - 31 (2007/10/03)
The reactions of sec-aminodienylesters 2, which were prepared by the reactions of methyl 5-(N,N-dimethylamino)2,4-pentadienoate (tert- aminodienylester 1) with primary amines, with acetaldehyde afforded 2,3- dihydro-6H-1,3-oxazines 3, providing a new heterocyclic annelation reaction.
