Formula: C24H40N4O4Rh2. 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. Compound: Dirhodium(II) tetrakis(caprolactam), is researched, Molecular C24H40N4O4Rh2, CAS is 138984-26-6, about Di- and trisubstituted γ-lactams via Rh(II)-carbenoid reaction of N-Cα-branched, N-bis(trimethylsilyl)methyl α-diazoamides. synthesis of (±)-α-allokainic acid.
Acyclic N-Cα-branched, N-bis(trimethylsilyl)methyl (N-BTMSM) diazoamides undergo regio-, chemo-, and diastereoselective Rh(II)-carbenoid C-H insertion to give 4,5-disubstituted and 3,4,5-trisubstituted γ-lactams. The conformational influence of the N-BTMSM group and the electronic effect of the O-pivaloyl moiety of the Cα-oxymethylene unit are essential for the observed regioselectivity. The synthesis of α-allokainic acid demonstrates the utility of the method.
