In an article, author is Zhu, Min, once mentioned the application of 174671-46-6, COA of Formula: https://www.ambeed.com/products/174671-46-6.html, Name is AN-2690, molecular formula is C7H6BFO2, molecular weight is 151.93, MDL number is MFCD10699483, category is indole-building-block. Now introduce a scientific discovery about this category.
Herein we report visible-light-induced intramolecular double dearomative cycloaddition of arenes. Compared with the well-known photodimerization of arenes under ultraviolet irradiation, the current reactions are carried out under mild conditions and feature wide substrate scope. A large array of structurally-diverse polycyclic indoline derivatives is afforded in high yields (up to 98 %) with exclusive diastereoselectivity (>20:1 dr) via dearomative [4+2] or [2+2] pathway.
If you are interested in 174671-46-6, you can contact me at any time and look forward to more communication. COA of Formula: https://www.ambeed.com/products/174671-46-6.html.
