Краткое описание
The reaction of dimethyl 2-methyl- and dimethyl 2-phenyl-4-oxo-4 H -chromen-3-yl-phosphonate with various aliphatic and aromatic amines was investigated. A novel class of cyclic phosphonic analogues of chromone, 1 (2-methoxy-3-[1-(alkylamino)ethylidene or benzylidene]-2,3-dihydro-2,4-dioxo-2 λ 5 -benzo[e]-[1,2]oxaphosphinane), was obtained when primary amines were used as nucleophiles. An analogous reaction with aromatic or secondary amines led to the hydrolysis of one methyl ester group in the phosphonic acid residue.
