The latter can easily be obtained in the individual state when the reaction is carried out in the presence of triethylamine. In the case of primary aliphatic amines, the open-chain reaction product immediately undergoes cyclization into 3-alkyliminomethyl-2-aminochromones. The structures of the products were examined by 1D and 2D 1H, 13C, and 15N NMR spectroscopy in DMSO-d6 and CDCl3 Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Moshkin, V.
