  摘要：

  The reactions of aminals, the Mannich bases, and azomethines derived from substituted salicylaldehydes were studied. Derivatives of tetrahydrocyclopenta[b]- and hexahydro-cyclohepta[b]chromenes and substituted 2,2'-spirobichromenes were prepared from aminals, and substituted hexahydroxanthenes were synthesized from the Mannich bases. Azomethine derivatives of 5-nitrosalicylaldehyde and aliphatic amines react with cyclohexanone to form 4a-amino-7-nitro-2,3,4,4a-tetrahydro-1H-xanthenes. 4a-Morpholino-7-nitro-9-phenylethynyl-1,2,3,4,9,9a-hexahydroxanthene was studied by X-ray diffraction analysis.

  Decarboxylative A3-coupling of ortho-hydroxybenzaldehydes, secondary amines, and alkynoic acids is performed under catalyst and solvent-free conditions. The developed methodology provided a waste-free method for the synthesis of hydroxylated propargylamines which are versatile precursors for various bioactive heterocyclic scaffolds. The experimental and density functional theory studies revealed that

  Potassium alkynyltrifluoroborates react with amines and salicylaldehydes in the presence of benzoic acid to generate highly functionalized amines. Ionic liquids such as butylmethylimidazolium tetrafluoroborate (BmimBF(4)) are suitable solvents for the reaction. (C) 2003 Elsevier Ltd. All rights reserved.
