[摘要]:A cationic rhodium(I)/Segphos or H8-BINAP complex catalyzes the unprecedented cotrimerization of com. available monoenes and dialkyl acetylenedicarboxylates, leading to functionalized furylcyclopropanes, e.g. I (E = CO2R, R = Me, Et), with excellent enantioselectivity and perfect diastereoselectivity. |
