Electric Literature of C46H46O4P2Pd2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium, is researched, Molecular C46H46O4P2Pd2, CAS is 172418-32-5, about Efficient synthesis of six-membered ring D analogs of the pentacyclic alkaloid cephalotaxine by two palladium-catalyzed reactions. Author is Tietze, Lutz F.; Schirok, Hartmut; Wohrmann, Michael; Schrader, Klaus.
D-homo-Cephalotaxine analogs I and II have been prepared by intramol. Heck reactions of III (m = 0, 1, 2; n= 1, 2; X = Br, I) and IV (m = 1, 2; n = 1, 2). The substrates III and IV were obtained by alkylation and acylation, resp., of the spirocyclic amines V (n = 1, 2), which, in turn, were generated by intramol. palladium-catalyzed allylic amination.
This compound(trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium)Electric Literature of C46H46O4P2Pd2 was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
