, p. 221 - 225 (2001)
Ethyl 3,4-dihydro-2H-1,4-benzoxazine-3-carboxylate derivatives 2 were obtained and isolated in low yields from the condensation of 2-aminophenol and ethyl 2,3-dibromopropanoate. They can be obtained by hydrogenation of ethyl 2H-1,4-benzoxazine-3-carboxyla
Synthesis and biological evaluation of new 2-(4,5-dihydro-1H-imidazol-2-yl)-3,4-dihydro-2H-1,4-benzoxazine derivatives

2-(4,5-Dihydro-1H-imidazol-2-yl)-3,4-dihydro-2H-1,4-benzoxazine derivatives and tricyclic analogues with a fused additional ring on the nitrogen atom of the benzoxazine moiety have been prepared and evaluated for their cardiovascular effects as potential antihypertensive agents. The imidazoline ring was generated by reaction of the corresponding ethyl ester with ethylenediamine. Affinities for imidazoline binding sites (IBS) I1 and I2 and α1 and α2 adrenergic receptors were evaluated as well as the effects on mean arterial blood pressure (MAP) and heart rate (HR) of spontaneously hypertensive rats. With few exceptions the most active compounds on MAP were those with high affinities for IBS and α2 receptor. Among these, compound 4h was the most interesting and is now, together with its enantiomers, under complementary pharmacological evaluation.
A straightforward route to 4H-1,4-benzoxazine-2-carbaldehydes by Swern oxidation
Bourlot, Anne-Sophie,Guillaumet, Gerald,Merour, Jean-Yves
, p. 191 - 196 (2007/10/03)
Swern oxidation of saturated (1,4-benzoxazine-2-yl)-methanols 2 furnished 4H-1,4-benzoxazine-2-carbaldehydes 3, which possess an α,β ethylenic bond. The reactivity of these compounds was examined.
