  MILD AND CONVENIENT ONE POT SYNTHESIS OFN-HYDROXYIMIDES FROMN-UNSUBSTITUTED IMIDES

  摘要：

  A new, one pot synthesis of various N-hydroxyimides from N-unsubstituted imides is described. Imides are first transformed into their N-Boc derivatives, which are next reacted with aqueous hydroxylamine, providing crystalline hydroxylammonium salts of the corresponding N-hydroxyimides. Filtration and acidic workup affords pure N-hydroxyimides.

  Catalytic enantioselective formation of methylenelactam-based N,O-spirocyclic compounds is developed. Hydroxylactams prepared from N-carbonyl phthalimides and β-amido functionalized allylboronates underwent ring opening-asymmetric reclosure in the presence of catalytic amounts of MgBr2 and a chiral aminophenol to afford the corresponding N,O-spirocyclic compounds in excellent yields and high enantioselectivities

  This communication describes the utility of β-amido allylboronate as a nucleophile in the catalytic amide allylation of N-carbonyl imides. The reaction of the imide substrates with the boronates has been accomplished by using catalytic zinc bromide and basic additives (ethanol, potassium carbonate and 18-crown 6-ether), affording azaspiro-γ-lactones through a ring opening-reclosure process with yields
