Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Synthesis called Copper-catalyzed skeletal rearrangement of O-propargylic aryloximes into four-membered cyclic nitrones – chirality transfer and mechanistic insight, Author is Nakamura, Itaru; Kudo, Yu; Araki, Toshiharu; Zhang, Dong; Kwon, Eunsang; Terada, Masahiro, which mentions a compound: 32717-95-6, SMILESS is C12=C(CCC3=C4CC2)[Cu+]1534[Cl-][Cu+]678(C9=C6CCC7=C8CC9)[Cl-]5, Molecular C16H16Cl2Cu2, Formula: C16H16Cl2Cu2.
Cu-catalyzed skeletal rearrangement of (E)-configurated O-propargylic aryl oximes were carried out to afford the corresponding 4-membered cyclic nitrones in good to excellent yields. The optimal reaction conditions of the highly regioselective reactions involved the use of [CuCl(cod)]2 in MeCN at 70°. In the case of (Z)-configurated derivatives, however, the reaction proceeded in the absence of the Cu catalysts to afford the identical compound in good yields. Furthermore, the reactions were also carried out using chiral substrates in the presence of Cu catalysts to afford the corresponding products with good levels of chirality transfer.
