  (η3-1- and 2-Trimethylsiloxyallyl)Fe(CO)2NO complexes were prepared by the reaction of the corresponding siloxyallylic halides with Bu4N[Fe(CO)3NO]. These complexes reacted with both of carbon nucleophiles and carbon electrophiles preferentially at the less hindered sites of the allylic ligands. In these reactions, (η3-1-trimethylsiloxyallyl)Fe(CO)2NO complexes served as synthetically equivalent synthons

  (η3-1-和2-三甲基甲硅烷氧基烯丙基)Fe(CO)2NO配合物是通过相应的甲硅烷氧基烯丙基卤化物与Bu4N[Fe(CO)3NO]反应制备的。这些配合物优先与碳亲核试剂和碳亲电试剂在烯丙基配体的受阻较小的位点反应。在这些反应中，(η3-1-三甲基甲硅烷氧基烯丙基)Fe(CO)2NO 配合物作为 β-酰基碳正离子和 j8-酰基碳负离子和 (η3-2-三甲基甲硅烷氧基烯丙基)Fe(CO)2NO 配合物的合成等效合成子α-酰基碳正离子和α-酰基碳负离子。描述了反应的立体化学过程。

  reaction of allene-tethered dithiosemicarbazides 4 is a convenient method for the preparation of five-membered unsaturated nitrogen heterocycles. The sulfur-directed intermolecular attack of the tin radical at the semicarbazide moiety leads to an allene-tethered iminyl radical, which then undergoes a 5-exo-dig cyclization leading to both the 3H-pyrroles 5 and the alkylidene pyrrolines 6; thermal isomerization

  The present invention relates to prodrugs of a wide variety of drugs and pharmaceutical compositions containing such prodrugs. Methods for minimizing locally mediated (from within the gut lumen) adverse gastrointestinal events associated with the underivatised drug and increasing the sustainment of plasma drug levels with the aforementioned prodrugs are also provided. Thus, the present invention relates to the use of prodrugs of a wide diversity of drugs (other than opioids) to transiently inactivate them and so reduce directly, locally mediated adverse gastrointestinal (GI) side-effects normally evident after administration of the parent compound. Additionally, such prodrugs may confer improved pharmacokinetics.
