NEW CROWN-ETHER DIBENZO-18-CROWN-4 LIGAND VIA SEQUENTIAL ONE-POT REACTION

A friendly synthetic rout for a new GI-PRO crown-ether was developed in this short communication.The method in question was able to produce the desirable product in high yields (up to 80%), even after some purification steps.The crown-ether, named DB18C4 (Dibenzo-18-crown-4) was fully characterized by different spectroscopic and spectrometric metho

This study prospectively evaluated the diagnostic value of unenhanced computerized tomography (CT) urography in patients with acute renal colic.Fifty-nine patients with clinical manifestations of acute renal colic underwent unenhanced helical CT to evaluate urinary tract abnormalities.Reformatted three-dimensional CT urography was performed in all
