Category: indole-building-block. I found the field of Chemistry very interesting. Saw the article Diastereoselective Synthesis of Dihydro-quinolin-4-ones by a Borane-Catalyzed Redox-Neutral endo-1,7-Hydride Shift published in 2021.0, Reprint Addresses Paradies, J (corresponding author), Paderborn Univ, Chem Dept, D-33098 Paderborn, Germany.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde.
The borane-catalyzed synthesis of dihydroquinoline-4-ones is developed. The amino-substituted chalcones undergo a 1,7-hydride shift upon Lewis acid activation to form a zwitterionic iminium enolate, which collapses to the dihydroquinoline-4-one scaffold. The reaction proceeds in high yields (75-99%) with an excellent diastereoselectivity of up to >99:1 (cis:trans). The reaction mechanism is investigated by kinetic, isotope labeling, and computational experiments.
