(三羰基)铁与无环二烯的络合用于保护配体免受氧化、还原和环加成反应，而该助剂的空间体积用于引导试剂接近连接到二烯的与铁相反的面上的不饱和基团。此外，Fe(CO)3 部分可以稳定与二烯相邻的碳阳离子中心（即戊二烯基铁阳离子）。介绍了这些反应性在合成含多烯、环丙烷、环庚二烯和环己烯酮的天然产物或类似物中的最新应用。 (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, 德国, 2009)
Complexation of (tricarbonyl)iron to an acyclic diene serves to protect the ligand against oxidation, reduction, and cycloaddition reactions, whereas the steric bulk of this adjunct serves to direct the approaches of reagents to unsaturated groups attached to the diene onto the face opposite to iron. Furthermore, the Fe(CO)3moiety can serve to stabilize carbocation centers adjacent to the diene (i.e. pentadienyl‐iron cations). Recent applications of these reactivities to the synthesis of polyene‐, cyclopropane‐, cycloheptadiene‐, and cyclohexenone‐containing natural products or analogues are presented.
