Zhao, Rongrong published the artcileBis(2-methoxyethyl)ether promoted intramolecular acceptorless dehydrogenative coupling to construct structurally diverse quinazolinones by molecular oxygen, Safety of 1,2-Diphenyl-1H-benzo[d]imidazole, the publication is Green Chemistry (2022), 24(4), 1644-1649, database is CAplus.
A simple, efficient and clean approach for the synthesis of diverse dihydroisoquinolino[2,1-a]quinazolinones, 2-aryl quinazolinones and analogs through intramol. acceptorless dehydrogenative coupling has been achieved. The combination of bis(2-methoxyethyl)ether and mol. oxygen was identified as a highly efficient system for this oxidative dehydrogenative coupling sequential transformation without an external initiator, catalyst and additive. The applicability and practicability were demonstrated by a scope of twenty-nine examples and a gram-scale reaction. Some control experiments were also conducted to support a possible reaction pathway.
