5-amino-2-hydroxybenzoate or 1-aminonaphthalene by using NaNO2 in the presence of HCl afforded diazonium salt derivatives 2 and 5, which were treated with substituted imino or substituted amino derivatives, to give the corresponding substituted amino-pent-2-en-3-yl-diazenylbenzoate 4a–k or 2-substituted-1-(naphthalen-1-yl)diazene derivatives 6a–h, 7a,b, and 8a,b. All the synthesized compounds were

The synthesis of previously unreported 2-arylimino-2H-pyrancarboxaldehydes is achieved by the treatment of Vilsmeier reagent with N-arylacetoacetamides. 2-N-Alkyl and the parent 2-imino-2H-pyrancarboxaldehyde derivatives are synthesized from the corresponding acetoacetamide derivatives. A possible mechanism for the formation of 2-imino-2H-pyrancarboxaldehyde is discussed.

A general, efficient and rapidmethod for the synthesis of various β-carboxamide derivatives using microwaveirradiation is described. Excellent isolated yields were obtained in very short reaction times when conventional heating was replaced by microwaveirradiation.
Enamine-Based Domino Strategy for C-Acylation/Deacetylation of Acetoacetamides: A Practical Synthesis of β-Keto Amides

A practical three-step route for C-acylation/deacetylation of acetoacetamides is described. Initial enamination of the acetoacetamides with Boc-monoprotected ethylenediamine provides β-enamino amides, which are acylated at the α-carbon with excellent selectivity. The C-acylated derivatives undergo domino fragmentation in acidic media to give the corresponding α-Keto amides accompanied by 2-methyl-4
