Abstract

The π-allyltricarbonyliron lactone complex (7), formed by reaction of E-1, 2-epoxy-2-methyl- 6, 6-dimethoxyhex-3-ene (5) with co-ordinatively unsaturated iron carbonyl species, was reacted with benzylamine to give a lactam complex (8) by an SN'-like mechanism. This complex upon oxidation with Ce (IV) afforded cis-3-isopropenyl-4-[(2', 2'-dim (9) which was chemically modified into trans-3-(1'-hydroxyethyl)-4-[(2', 2-dimethoxy) ethyl] azetidin-2-one ...
