Synthesis and study of glycoluril derivatives

Improve and illustrate the etherification of tetramethylol glycoluril using excess of methyl and ethyl alcohols in the presence of acid catalyst like HCl and HNO3 under temperature not exceeding 55 °C. Furthermore, attempts to obtain 1,4-diphenyl 1,2-dimethylol glycoluril which is a new compound from the condensation of 1,4 diphenyl glycoluril with formaldehyde in the presence of water under mild temperature. The techniques used to identify the compounds of the present study are: FTIR spectroscopy, HPLC and 13C NMR spectroscopy.
