carbonyls by reductive electron transfer are exploited in carbon–carbon bond formation. New radical cyclizations of urea radical anions deliver complex nitrogen heterocycles and, depending upon the proton source used in the reactions, a chemoselective switch between reaction pathways can deliver two heterobicyclic scaffolds. A computational study has been used to investigate the selectivity of the urea
通过还原电子转移从脲羰基生成的自由基阴离子被用于碳-碳键的形成。尿素自由基阴离子的新的自由基环化传递复杂的氮杂环,并且根据反应中使用的质子来源,反应路径之间的化学选择性转换可以传递两个杂环双环骨架。已经使用计算研究来研究尿素自由基过程的选择性。此外,涉及脲自由基阴离子的自由基环化级联反应提供了不同寻常的螺环氨基结构。
