A novel methodology for the synthesis of guanidines from amines has been developed using polymer assisted synthesis, potentially allowing the preparation of series of compounds in a high throughput manner. The methodology comprises the use of polymer-supported carbodiimide as the activating agent for N,N′-bis(tert-butoxycarbonyl) thiourea with polymer-supported trisamine as a scavenger, followed by

radiosensitizers to improve the therapeutic outcomes of radiotherapy in cancer patients. Our previous efforts to identify novel radiosensitizers, using high-throughput screening targeting p53 and Nrf2 revealed a promising N-phenylpyrimidin-2-amine (PPA) lead compound. In the present study, 17 derivatives of this lead compound were examined, and it was found that 4-(4-fluorophenyl)-N-(4-nitrophenyl)-6-phenylpyrimidin-2-amine

Abstract A new method for the solid‐phasesynthesis of N‐aryl‐N′‐carboalkoxy guanidines is described. Aromatic amines were reacted with Fmoc‐isothiocyanate to provide Fmoc‐thioureas, which were coupled with Rink amide resin to provide the corresponding resin‐bound Fmoc‐guanidines. Subsequent Mitsunobu alkylation with a variety of alcohols delivered N‐aryl‐N′ carboalkoxy guanidines in good to high purity
