Synthetic Route of C5H7Br. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about Gold-Catalyzed Domino Cycloisomerization/Alkoxylation: An Entry to 3,4-Dihydro-1H-[1,4]oxazino[4,3-a]indole. Author is Dupeux, Aurelien; Michelet, Veronique.
A novel and mild synthetic route for the preparation of functionalized polycyclic indole skeletons via a gold-mediated cycloisomerization/alkoxylation of 1,6-aldehyde-yne had been developed. This atom-economical catalytic process that associates IPrAu(MeCN)BF4 and an alc. demonstrated remarkable selectivity in accessing functionalized 3,4-dihydro-1H-[1,4]oxazino[4,3-a]indole derivatives I [R1 = H, Et, Ph, etc.; R2 = H, Me, Br; R3 = H, Cl; R4 = Me, i-Pr, CH2CH=CH2, Bn, CH2CH(CH3)CH2CH3, CH2CH=CCH2CH2CH=C(Me)2] of high synthetic utility (21 examples, yields of ≤96%) and could be optimized under asym. conditions with an enantiomeric excess of ≤86%.
After consulting a lot of data, we found that this compound(16400-32-1)Synthetic Route of C5H7Br can be used in many types of reactions. And in most cases, this compound has more advantages.
