  Synthesis of 3-substituted N-allylisoindolinone derivatives by the acetate method

  摘要：

  A series of N-allylisoindolinone derivatives were prepared by a novel sequential reaction of 2-allyl-3-oxoisoindolin-1-yl acetate with C-nucleophiles in the presence of trimethylsilyl trifluoromethanesulfonate. The nucleophiles included arenes, alkenes, and active methylene to give 3-substituted N-allylisoindolinone products. This method was applied to synthesize cyclohexane-fused indolizidine alkaloid mimics using Grubbs' catalyst..

  N-酰基亚胺离子化学中的多金属铱锡（Ir-Sn 3）催化剂：通过分子内和分子间酰胺基烷基化反应合成3-取代的异吲哚满酮

  摘要：

  AbstractThe multimetallic iridium‐tritin (Ir‐Sn3) complex [Cp*Ir(SnCl3)2{SnCl2(H2O)2}] (1) proved to be a highly effective catalyst towards COH bond activation of γ‐hydroxylactams, leading to a nucleophilic substitution reaction known as the α‐amidoalkylation reaction. Catalyst 1 can be easily synthesized from the reaction of (pentamethylcyclocyclopentadienyl)iridium dichloride dimer {[Cp*IrCl2]2} and tin(II) dichloride (SnCl2). In terms of catalyst loading, reaction conditions and yields of the product formed, 1 is found to be superior compared to classical Lewis acid catalysts. Different carbon (arenes, heteroarenes, allyltrimethylsilane, 1,3‐dicarbonyls) and heteroatom (alcohols, thiols, amides and sulfonamides) nucleophiles have been successfully employed in the intramolecular and intermolecular alkylations, as well as in heterocyclization reactions. In the majority of cases good to excellent yields of 3‐substituted isoindolinones and 5‐substituted pyrrolidin‐2‐ones have been obtained. Besides, the reactions are also atom economical and salt free. It is proposed that the multimetallic Ir‐Sn3 catalyst behaves as a mild and selective Lewis acid to activate the γ‐hydroxylactam towards the formation of the N‐acyliminium ion; the latter being trapped by potent nucleophiles leading to the desired products.magnified image

  Cyclic imides were selectively reduced to the corresponding ω‐hydroxylactams in high yields with (EtO)3SiH (triethoxysilane) or PMHS (polymethylhydrosiloxane) under catalysis of zinc diacetate dehydrate [Zn(OAc)2⋅2 H2O] (10%) and tetramethylethylenediamine (TMEDA) (10%). This catalytic protocol showed good functional group tolerance as well as excellent regioselectivity for unsymmetrical imides bearing

  and practical electrochemical method for selective reduction of cyclic imides has been developed using a simple undivided cell with carbon electrodes at room temperature. The reaction provides a useful strategy for the rapid synthesis of hydroxylactams and lactams in a controllable manner, which is tuned by electric current and reaction time, and exhibits broad substrate scope and high functional group
