Abstract Invasive ants pose a risk to human well-being and social/ecosystem stability. Linepithema humile Mayr is among the most damaging invasive ants worldwide. Most L. humile populations invade ports/wharfs isolated from surrounding landscapes, bu

Electron-Poor Chiral Diphosphine Ligands: High Performance for Rh-Catalyzed Asymmetric 1,4-Addition of Arylboronic Acids at Room Temperature

Autor: Kazutaka Osaki, Ryota Maenishi, Takashi Sakai, Toshinobu Korenaga

Publikováno v: Organic Letters. 11:2325-2328

Electron-poor chiral diphosphine ligands, MeO-F(28)-BIPHEP (1a) and MeO-F(12)-BIPHEP (1b), were synthesized for controlling a transition-metal catalyst electronically. The 1b-ligated Rh catalyst showed excellent catalytic activity with high % ee for

Highly Active Rhodium Catalyst with Electron-Poor Diphosphine Enables Efficient Synthesis of Chiral 4-Aryl-δ-lactones

Autor: Takashi Sakai, Toshinobu Korenaga, Ryota Maenishi, Kazutaka Osaki

Publikováno v: HETEROCYCLES. 80:157

Chiral 4-aryl-δ-lactones could be synthesized efficiently with high enantioselectivity through asymmetric 1,4-addition of arylboronic acid to α,β-unsaturated lactones using Rh catalyst including electron-poor diphosphine (MeO-F 12 -BIPHEP) at room
