Lanthanide-catalyzed cyclocarbonylation and cyclothiocarbonylation: a facile synthesis of benzannulated 1,3-diheteroatom five- and six-membered heterocycles

Green Catalyst‐ and Additive‐Free Three‐Component Deamination Cyclization Synthesis of 3‐Substituted‐4‐ oxo‐2‐quinazolinonyl Sulfides

“…Next, compound 1 a was first reacted with 2 a for 12 h to give the intermediate 7 in 83 % isolated yield, which was also confirmed by NMR. [22] Then, 3 a was introduced into the reaction system under the standard conditions to generate the desired compound 4 a in 72 % yield, indicating that 7 might be a possible intermediate in this chemical process (Scheme 5,d).…”

A Review on Domino Condensation/Cyclization Reactions for the Synthesis of 2‐Substituted 1,3‐Benzothiazole Derivatives

“…Lin and co‐workers developed an effective synthesis of various benzo‐fused 1,3‐di‐heteroatomic cyclic ketones via organolanthanide‐catalyzed cyclocarbonylation of bifunctional arenes with isocyanates [Eq. (33)].…”

Lanthanides and actinides: Annual survey of their organometallic chemistry covering the year 2014

“…[118] M a n u s c r i p t The selective hydrosilylation of CO 2 to a bis(silylacetal) using an anilidobipyridylligated organoscandium catalyst has been investigated in great detail. Ligand attachment M a n u s c r i p t 105 by alkane elimination from a scandium trialkyl precursor resulted in metalation of an aryl C-H bond in a 3,5-di-tert-butylphenyl group on the pyridyl unit, resulting in a tetradentate coordination of the ligand.…”
