The synthesis of β-ionone analog tricarbonyliron complexes was investigated. N-Methoxy-N-methyl-(2, 6, 6-trimethyl-1-cyclohexen-1-yl)-2-propenamide (Weinreb amide), prepared from the corresponding ethyl ester and N, O-dimethylhydroxylamine hydrochloride, reacted smoothly with various organometallic reagents to afford the β-ionone analogs in good to excellent yields. Treatment of these compounds with dodecacarbonyltriiron afforded the corresponding tricarbonyliron complexes in high yields.
研究了β-紫罗兰酮类似物三羰基铁配合物的合成。由相应的乙酯与N,O-二甲基羟胺盐酸盐制备N-甲氧基-N-甲基-(2,6,6-三甲基-1-环己烯-1-基)-2-丙烯酰胺(Weinreb酰胺),反应顺利与各种有机金属试剂反应,以良好至优异的产率提供 β-紫罗兰酮类似物。用十二羰基三铁处理这些化合物以高产率得到相应的三羰基三铁配合物。
