So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Maksymowicz, Rebecca M.; Roth, Philippe M. C.; Thompson, Amber L.; Fletcher, Stephen P. researched the compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine( cas:415918-91-1 ).Product Details of 415918-91-1.They published the article 《Hydrometallation-asymmetric conjugate addition: application to complex molecule synthesis》 about this compound( cas:415918-91-1 ) in Chemical Communications (Cambridge, United Kingdom). Keywords: alkene hydrometalation stereoselective conjugate addition enone steroid copper catalyst. We’ll tell you more about this compound (cas:415918-91-1).
Copper catalysis allows alkyl zirconium species, generated in situ from alkenes, to undergo conjugate addition reactions. A hydrometalation-catalytic asym. 1,4-addition was used to synthesize either enantiomer of a natural product in one step from com. available materials. Hydrometalation-addition sequences applied to steroids containing a cross-conjugated dienone or 1,6-acceptor give highly functionalized products.
