The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine(SMILESS: C[C@@H](N(P1OC2=CC=C3C=CC=CC3=C2C4=C5C=CC=CC5=CC=C4O1)[C@@H](C6=CC=CC=C6)C)C7=CC=CC=C7,cas:415918-91-1) is researched.Related Products of 610-09-3. The article 《Hydrovinylation of Norbornene. Ligand-Dependent Selectivity and Asymmetric Variations》 in relation to this compound, is published in Organic Letters. Let’s take a look at the latest research on this compound (cas:415918-91-1).
Norbornene undergoes Ni-catalyzed (1-2 mol% allylnickel bromide/phosphine/NaBARF, sodium tetrakis[3,5-bis(trifluormethyl)phenyl]borate or AgSbF6, 1 bar ethylene, -50 °C) hydrovinylation (>97% yield), giving either a 1:1 or a 2:1 (norbornene/ethylene) adduct depending on the size of the phosphine. Use of binaphthol-derived phosphoramidite ligand results in up to 80% ee for the 1:1 adduct. The course of the reaction is highly dependent on the ligand (size and configuration of the appendages) and the counteranion present.
There is still a lot of research devoted to this compound(SMILES：C[C@@H](N(P1OC2=CC=C3C=CC=CC3=C2C4=C5C=CC=CC5=CC=C4O1)[C@@H](C6=CC=CC=C6)C)C7=CC=CC=C7)Product Details of 415918-91-1, and with the development of science, more effects of this compound(415918-91-1) can be discovered.
