An efficient method has been successfully developed to achieve the asymmetric C–H functionalization of indoles in the carbocyclic ring via organocatalysis, and a variety of tetrahydropyranoindoles were synthesized in good yields with excellent stereoselectivities. Further study on thermodynamic calculations indicated that the process was promoted by generating more thermodynamically stable products
已经成功开发了一种有效的方法,可以通过有机催化实现碳环中
吲哚的不对称C–H功能化,并且以良好的收率和良好的立体选择性合成了各种
四氢吡喃并
吲哚。对热力学计算的进一步研究表明,该过程是通过产生更多热力学稳定的产物来促进的。这种策略,加上传统的羟基
吲哚的C-3官能化,可以实现
吲哚的可切换,区域发散的不对称修饰。
