Introducing a new discovery about 22013-33-8, Name is 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine
A simple and straightforward method for facile access to coumarin-fused dihydroquinolines (4) has been developed using the microwave-assisted multicomponent reactions of 4-hydroxycoumarin, aldehydes and aromatic amines in water catalyzed by bismuth triflate. Under solvent-free and conventional heating conditions, the same combination provided the corresponding coumarin-fused quinolines (5). An alternative and rapid method for the conversion of (4) to (5) with very good yields was also developed using N-bromosuccinamide. Single-crystal X-ray crystallographic analysis of one of the products (4q) showed that the products are regioselective and that the reactions proceed via 1,2-addition followed by 6pi-electrocyclization instead of a Skraup-Doebner-von Miller type reaction. Substituted quinoline carboxylic acid derivatives (7) were synthesized selectively from (4) by ring opening of the coumarin moiety followed by aromatization using NaOH/DMSO under reflux conditions. Considering the presence of the polycyclic conjugated structure of the synthesized compounds 4 and 5 with the coumarin moiety, preliminary photophysical studies were carried out and promising quantum yields were observed along with a maximum quantum yield (of = 0.65) for 4j.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C8H9NO2, you can also check out more blogs about22013-33-8
