Computed Properties of C46H46O4P2Pd2. 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: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium, is researched, Molecular C46H46O4P2Pd2, CAS is 172418-32-5, about Synthesis of 8,9-(1,3-benzodioxolo-5,6)-5-azatricyclo[8.2.1.01,5]tridec-11-en-6-one. A convenient route to structural analogs of the alkaloid cephalotaxine. Author is Kuznetsov, N. Yu.; Zhun’, I. V.; Khrustalev, V. N.; Bubnov, Yu. N..
A synthetic route to 8,9-(1,3-benzodioxolo-5,6)-5-azatricyclo[8.2.1.01,5]tridec-11-en-6-one, structurally isomeric to the pentacyclic cephalotaxine nucleus, is suggested. The route is based on the sequences including diallylboration of 2-pyrrolidinone and intramol. metathesis of the resulting 2,2-diallylpyrrolidine, giving rise to 1-azaspiro[4.4]non-7-ene. This product was N-acylated with 6-bromohomopiperonylic acid chloride and then subjected to intramol. cyclization according to the Heck reaction.
As far as I know, this compound(172418-32-5)Computed Properties of C46H46O4P2Pd2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
