Organocatalytic amination of alkyl ethers via n-Bu4NI/t-BuOOH-mediated intermolecular oxidative C(sp3)-N bond formation: novel synthesis of hemiaminal ethers

25 August, 2014 - 23:54

Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC05758A, CommunicationLongyang Dian, Sisi Wang, Daisy Zhang-Negrerie, Yunfei Du, Kang Zhao
A novel method for constructing the hemiaminal ether framework under metal-free conditions has been developed. It involves direct organocatalytic amination of alkyl ethers through intermolecular oxidative C(sp3)-N bond formation, with t-BuOOH being the oxidant and n-Bu4NI as the catalyst.

Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC05401F, CommunicationYuanyuan An, Danqing Zheng, Jie Wu
A three-component reaction of 2-(allyloxy)anilines, sulfur dioxide and hydrazines under mild conditions is developed, which gives rise to 1-(2,3-dihydrobenzofuran-3-yl)-methanesulfonohydrazides in good yields. This radical process involves an intramolecular 5-exo-cyclization and insertion of sulfur dioxide.
