Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 138984-26-6, is researched, SMILESS is C12=O[Rh+2]3(O=C4[N-]5CCCCC4)([N-]6C(CCCCC6)=O7)[N-](CCCCC8)C8=O[Rh+2]357[N-]1CCCCC2, Molecular C24H40N4O4Rh2Journal, Article, Research Support, U.S. Gov’t, P.H.S., Organic Letters called Lewis Acid/Rhodium-Catalyzed Formal [3 + 3]-Cycloaddition of Enoldiazoacetates with Donor-Acceptor Cyclopropanes, Author is Cheng, Qing-Qing; Qian, Yu; Zavalij, Peter Y.; Doyle, Michael P., the main research direction is Lewis acid rhodium catalyzed cycloaddition enoldiazoacetate donor acceptor cyclopropane; diastereoselective cycloaddition enoldiazoacetate donor acceptor cyclopropane; rhodium catalyzed chemoselective ring expansion.HPLC of Formula: 138984-26-6.
A formal [3 + 3]-cycloaddition of enoldiazoacetates with donor-acceptor cyclopropanes was realized by the combination of a Lewis acid-catalyzed diastereoselective [3 + 2]-cycloaddition [e.g., enol diazoacetate I + cyclopropane II in presence of Yb(OTf)3 → cyclopentane III (84% isolated yield, dr 10:1)] and a subsequent rhodium-catalyzed chemoselective ring expansion [III → IV (88%) in presence of Rh2(cap)4, cap = caprolactamate]. This tandem transformation provides an efficient approach to highly functionalized cyclohexenes.
In addition to the literature in the link below, there is a lot of literature about this compound(Dirhodium(II) tetrakis(caprolactam))HPLC of Formula: 138984-26-6, illustrating the importance and wide applicability of this compound(138984-26-6).
