DOI: 10.1039/c7cc07093d
Abstract: A traceless organosilicon template-directed meta-selective-C-H alkenylation of phenols was realized with good yields and high selectivities. The template was readily removable through F--promoted O-Si cleavage under extremely mild conditions or recyclable through a p-TSA catalyzed… read more here.

DOI: 10.1039/d4ra06210h
Abstract: An efficient synthetic method has been developed for C-3 site-selective alkenylation of indole derivatives under ruthenium(ii) catalysis with an ester as a directing group. Besides the presence of two potential C(sp2)–H sites available for functionalization… read more here.
