  Reactions of (η⁵-C₅H₅)(CO)₂Fe-Substituted N-Sulfonyl Azadienes with C-Nucleophiles. A Route to 5-Substituted Dihydropyrrolones

  摘要：

  A variety of cyclic beta-[(eta(5)-C5H5)(CO)(2)Fe]-substituted N-sulfonyl azadienes 4 were pre pared: e.g., from the corresponding iron-substituted (Z)-enals and benzenesulfonamide. Reactions of these iron compounds with Grignard reagents or organolithiums gave 5-substituted alpha,beta-unsaturated N-sulfonyl gamma-lactams 5. In some cases the corresponding non-N-protected 5-substituted gamma-lactams 6 were isolated as well. Key steps of these reaction cascades are the initial 1,2-addition to the imine moiety and the subsequent carbonylation step. The reaction of the chromene-iron complex 4e with (allyl)MgCl gave the (eta(3)-allyl)iron-gamma-lactam complex 8a with a ring-opened chromene framework. This complex was structurally characterized by X-ray analysis.
