| The dianion 48 is unlikely to cyclize, but cyclization could occur after proton transfer from another molecule of 44, thereby forming the enolate 49 which will not undergo any reduction. |
| The 2-aminophenoxy groups predispose the oligomers to cyclize as amic acids, and to remain as cyclics on imidization. |
| The photochromic dyes cyclize smoothly in polar organic solvents and water upon UV light irradiation while undergo fading under visible light. |
| These extensions, called cohesive ends, are complementary and enable the chromosome to cyclize in an infected cell. |
| Four molecules of this porphyrin precursor cyclize and undergo several side-chain modifications to yield the tetrapyrrole protoporphyrin. |
| The biradical can revert to the starting material, cyclize to give a cyclobutanol derivative, or in our case, fragment to an alkene and an enol component. |
