Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about 9α-Hydroxy-12-{[4-(4-hydroxyphenyl)piperazin-1-yl]methyl}-4,8-dimethyl-3,14-dioxatricyclo[9.3.0.02,4]tetradec-7-en-13-one.COA of Formula: C10H14N2O.
The title compound, C25H34N2O5, was synthesized from 9α-hydroxyparthenolide (9α-hydroxy-4,8-dimethyl-12-methylen-3,14-dioxa-tricyclo[9.3.0.02,4]tetradec-7-en-13-one), which in turn was isolated from the CHCl3 extract of the aerial parts of Anvillea radiata. Crystallog. data and at. coordinates are given. The mol. comprises a ten-membered ring fused to a five-membered ring with an addnl. epoxy ring system fused to the ten-membered ring. The five-membered ring also carries a 4-hydroxyphenyl-piperazin-1-ylmethyl substituent. The ten-membered ring adopts an approx. chair-chair conformation, while the piperazine ring displays a chair conformation and the five-membered ring shows an envelope conformation with the C atom closest to the hydroxy group forming the flap. Two C atoms in the Ph ring and the O atom of the hydroxyl group are disordered over two sites, with an occupancy ratio of 0.53(5):0.47(5). An intramol. O-H···N H-bond stabilizes the mol. conformation. In the crystal, C-H···O H bonds link the mols. into zigzag chains running along the a-axis direction.
After consulting a lot of data, we found that this compound(56621-48-8)COA of Formula: C10H14N2O can be used in many types of reactions. And in most cases, this compound has more advantages.
