Zhou, Jiao-Long; Ye, Meng-Chun; Sun, Xiu-Li; Tang, Yong published the article 《Trisoxazoline/Cu(II)-catalyzed asymmetric intramolecular Friedel-Crafts alkylation reaction of indoles》. Keywords: indole preparation triisopropyl borate substitution benzyl bromide coupling; indolyl alkylidene malonate preparation chiral trisoxazoline copper; asym intramol Friedel Crafts alkylation fused benzocarbazole stereoselective preparation; intramol asym Friedel Crafts alkylation catalyst chiral trisoxazoline copper.They researched the compound: 1-Boc-4-Bromoindole( cas:676448-17-2 ).Electric Literature of C13H14BrNO2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:676448-17-2) here.
Intramol. Friedel-Crafts alkylation reaction of indoles catalyzed by trisoxazoline/copper(II) is described. This annulation provides an easy access to polycyclic indole derivatives, e.g., I, with up to 90% ee in up to 99% yield.
Compounds in my other articles are similar to this one(1-Boc-4-Bromoindole)Electric Literature of C13H14BrNO2, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
