Computed Properties of C13H11NO2On June 3, 2016, Danda, Adithi; Kesava-Reddy, Naredla; Golz, Christopher; Strohmann, Carsten; Kumar, Kamal published an article in Organic Letters. The article was 《Asymmetric Roadmap to Diverse Polycyclic Benzopyrans via Phosphine-Catalyzed Enantioselective [4 + 2]-Annulation Reaction》. The article mentions the following:
The catalytic addition of the amino acid derived bifunctional N-acylaminophosphine to an α-substituted allene ester generated a zwitterionic dipole that engaged the vinylogous ester function of 3-cyanochromones in a [4 + 2] annulation reaction to deliver tetrahydroxanthones embodying three consecutive chiral centers in high yields and with excellent enantioselectivities. The established asym. synthesis further paves the way to two different classes of complex, sp3-rich tetracyclic benzopyrans via efficient cascade reactions. The experimental process involved the reaction of 6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile(cas: 50743-32-3Computed Properties of C13H11NO2)
6-Isopropyl-4-oxo-4H-chromene-3-carbonitrile(cas: 50743-32-3) belongs to nitriles. Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons.Computed Properties of C13H11NO2
