An efficient three-component reaction of 1-(2-aminoaryl)pyrroles, ethers, and elemental sulfur for constructing N-heterocycle-fused 1,3,6-benzothiadiazepines under transition-metal-free conditions has been developed. Ethers act as both reactants and solvent in this reaction. The method proceeds efficiently over a broad range of substrates with good functional group tolerance.
已经开发了一种在无过渡金属的条件下,由1-(2-氨基芳基)吡咯,醚和元素硫组成的高效三组分反应,用于构建N杂环稠合的1,3,6-苯并噻二氮杂ze。醚在该反应中既充当反应物又充当溶剂。该方法可在具有良好官能团耐受性的各种基材上有效地进行。
