Practical Synthesis of Unsymmetrical Ureas from Isopropenyl Carbamates
摘要:
[GRAPHICS]A very convenient method for the synthesis of unsymmetrical ureas is described, based on isopropenyl carbamates. The synthetic efficiency of traditional methods for urea formation, such as use of phosgene or alkyl and aryl carbamates, is limited by the formation of symmetrical urea side products or reaction reversibility. Isopropenyl carbamates react with amines cleanly and irreversibly and give unsymmetrical ureas in high yield and purity. This method is ideal for the rapid synthesis of compound libraries.
Naphthalene linked pyridyl urea as a supramolecular gelator: a new insight into naked eye detection of I<sup>−</sup>in the gel state with semiconducting behaviour
The gelation and anion responsive behavior of some 3-aminopyridinium-based molecules1–5have been examined. Compound2shows naked eye detection of I−in the gel state.
