Abstract:
In connection to our previous reports[1] regarding the auxine like effects of some phosphorin-2-oxide ring compounds, this study was concerned about a Mannich type syntheses involving p-isopropyl-phenyldichlorophosphine, o-aminophenol, 1,2-diaminopropan and acetone. A discussion about the products of the reactions, that are in fact a mixture of diastereomers, because of the existence of some stereogenic sites at the phosphorus and carbon atoms, was done.The newly obtained heterocyclic compounds were investigated regarding the development of chlorophyll a and b contents, in plants treated with different concentrations of the above-mentioned substances.
