Asymmetric cycloisomerization of nitrogen-bridged 1,6-enynes proceeded in the presence of a cationic rhodium complex coordinated with a chiral diene/phosphine tridentate ligand to give high yields of chiral 3-azabicyclo[4.1.0]heptenes with high enantioselectivity.
在阳离子铑配合物与手性二烯/膦三齿配体配位的情况下,进行氮桥1,6-烯炔的不对称环异构化,从而获得高对映选择性的手性3-氮杂双环[4.1.0]庚烯。
